Zay Jones Ever Changing Injury Diagnosis

Following today’s injury report and Zay Jones new injury diagnosis, this post will identify why it is an ankle injury and not solely a knee injury.

It’s a new day and a new injury report! Going into the Week 10 match up against the New Orleans Saints, the Buffalo Bills continue to get healthy to rebuild their depth just in time to take on a suddenly resurgent Drew Brees led offense and a surprisingly stingy defense. This week’s game will truly be a test to see if the Bills is the team that started 5-2 or if they are the Bills that lost to the Jets on Thursday night.

Today’s post will deviate from a general review of the injury report due to new and unexpected information released today courtesy of Chris Brown. It has been reported that the initial knee injury that WR Zay Jones sustained in Thursday nights loss is now classified as an ankle injury. My goal is to explain why there is a change in injury designation despite the obvious original injury.

As reported before, Jones injured his knee with a rather gruesome fall to the turf last Thursday. He was able to return and play, but left towards the end of the game after re-aggravating the injury. In one of my previous articles, I detailed the possible extent of the injury severity. As there was not any additional news that came out regarding further damage, it was assumed that he merely hyperextended his knee and that he may be limited.

However, the Buffalo Bills continue to throw curveballs with Chris Brown reporting that Jones’ knee injury is actually an ankle injury. When it comes from the Buffalo Bills, I’m not going to question the source. Now, everyone must be thinking, this doesn’t make any sense. And you’re right, it doesn’t make any sense. However, as the reader, you clicked on the right article as I will determine how this could be an ankle injury despite what happened to his knee.

To clarify, Zay Jones did injure his knee in Thursday night’s loss to the Jets. That is a fact, but how severe? Apparently not that severe considering it’s not listed on the official injury report and he was able to return. As for his ankle, I have reason to believe it is a high ankle sprain. Let me explain. The knee acts as a hinge joint, but the ankle has multiple planes of motion allowing for greater mobility, but decreased stability. Upon initial viewing of the injury, there are forward and side views of the mechanism of injury which offer greater insight.

As the 14 second clip plays, at around the 4-5 second mark, Jones trips over CB Buster Skrine’s leg and steps awkwardly with his right leg. However, as he plants, all his weight is being placed through his right leg. His foot is planted directly in the turf as he begins to fall forward with his knee hyperextending. His foot is in maximal dorsiflexion and eversion which translates in plain speak to the foot is maximally bent up and turned out partially. Finally, the knee buckles backwards, Zay vaults forward, and Zay goes down in pain.

Fortunately for Zay, the knee has an ability to lock out which is known as the screw home mechanism. This allows the knee to fully straighten and stay rigid. During the process, as the knee goes into full extension, a rotational component assists in fully extending. In Zay’s instance, the screw home mechanism was forced into action with the femur (thigh bone) internally rotating with the tibia (shin bone) externally rotating. The hyperextension accentuated this mechanism, placing maximal force through the knee with the remaining excess stress left was displaced back into the ankle joint.

As seen above in the picture, during normal walking, the tibia externally rotates, placing stress through the talus and calcaneus. The calcaneus is the heel bone and this is the portion that makes contact with the ground as the foot is supinating or bearing weight as in the supination diagram. The calcaneus is turned inward and the talus is dorsiflexed and abducted or bent up and pulled outward. These are normal biomechanics of the foot, but if placed through excess stress as in the case of Zay’s injury, this can cause a high ankle sprain as the mechanism of injury is extreme external rotation and dorsiflexion, which is what I believe occurred with Zay to get him the ankle injury designation. Think of this injury as a chain is only as strong as it’s weakest link. As the ankle is naturally more unstable, it is more susceptible to injury which is what happened in this case.

Considering other injuries, he may have sustained a medial ankle sprain or bone contusion according to the video. It may never be fully known the extent of his injury. This injury is confusing as it is not apparent to the naked eye. The manner in which way the knee bent is the obvious part of the injury. To the untrained eye, its hard to see, but upon further evaluation, it appears this may be a likely injury.

As I do not have insider information, only insider knowledge, I can say with only so much confidence that this is what occurred. Time will tell how this injury plays out and what further information is released. He may have also injured his ankle when he left the game the 2nd time and I have not seen video to support or refute the injury. I do not believe that this is something season ending or as serious as Clay’s injury in relation to time missed. He may miss some time depending on severity and how this week’s practice plays out.

Week 9 Recap- Jets & Zay’s Knee

Analysis of Zay Jones’ knee injury, Taiwan’s forearm, and a recap following the Jets game.

Whether you are a Bills fan or not, reading this, Thursday night was not a good game. Period. The offense never got moving until it was too late, the defense made Josh McCown look fantastic, and the Bills let one slip through their fingers. They’re now 5-3, 1 game back in the AFC East and currently holding the 1st wild card spot. Despite what the Bills fan base says after this loss, the sky is not falling. Every divisional game every year is a grind it out close game due to rivalry and pride. At the end of the day, the Bills came up short and now we will see how they respond. Last time they started 5-2, they lost 7 straight games. I don’t think this team is capable of a losing streak of that magnitude, but many men before me have been wrong.
Getting down to the injury side of things, it was one of the more rougher nights for the Bills this season. Several key players were returning from injury on a short week and several more key players sustained injury. First up is RB LeSean McCoy. McCoy injured his groin on the first offensive series of the game and had to leave briefly. McCoy was able to return shortly afterward but anyone could tell that he wasn’t the same. He lacked explosiveness, inability to cut hard, and unable to move the ball, rushing for only 25 yards. McCoy is the engine to our offense and if he goes down, then losses to the Jets are what happen. I don’t believe this will be a lingering issue as he was able to play the entire game and he has 10 days to rest. To add, he was able to run and perform some cutting, but lost the explosiveness he is known for. I would categorize this as a Grade 1 groin strain which should heal with proper management.
Next injury is WR Zay Jones. Jones suffered a right knee injury after being tripped late in the 2nd quarter. While trying to regain his footing and preventing falling down, Jones stepped awkwardly and hyperextended his knee, falling to the ground immediately. Upon initial observation, one may think ACL. The mechanism for injury was there but Jones avoided that. It appears as though he sustained a hyperextended knee, similar to what Bryce Harper sustained during this past MLB season. It is unknown whether he sustained a bone bruise similar to Harper but further evaluation is required.

Jones was remarkably able to return and play the rest of the game, hauling in several more passes before being injured again in the 4th quarter. There are several reasons why Jones was able to avoid the dreaded ACL tear. First, the knee acts as a hinge, similar to what is seen in a door. The knee bends and extends fully but with various forces, can go past their normal limits. In Jones case, his knee extended further than typically what is available. This injury happened due to the fact that he planted his right foot, attempting to stay upright while falling forward, leading to the joint to give.
Jones avoided a worse injury due to the fact that he was falling forward as he was planting his leg. His ankle joint was able to absorb some of the force, with the foot initially going into plantarflexion or pointed downward to stabilize as his knee was bending back. Thankfully, his foot did come up off the turf into dorsiflexion or bending up as he fell forward. Had his foot been stuck more in the turf or been hit directly through the knee, the injury would have been worse. Finally, it helps that he was not able to pivot to change directions laterally, leading to preservation of the ACL. In injuries such as this, there is concern for the PCL which prevents the knee from going backwards like that, but as he was able to return, it does not appear that he tore the PCL. There is concern for a PCL sprain or bone bruise upon further examination, but with the extended break, it may be inconsequential. As there is no updated information at this time noting severity, it is unknown whether he will miss any time. Chances are he won’t, but too early to tell. Either way, Zay Jones caught a very lucky break Thursday.
I’m overall surprised that he was able to return to the game and continue to run effectively after the injury. I believe that our medical staff would not put a player back out there that could risk further injury especially at a high level position. I did observe him wearing a compression sleeve but no bulky bracing which will assist for any swelling but provide minimal support.
Finally, Taiwan Jones got injured while trying to recover an onside kick late in the 4th quarter. Upon getting up to a seated position, the medical staff was supporting Jones’ left elbow indicating possible elbow injury or shoulder. Replays show that his arm got caught up in the pile and a helmet crashing into his forearm during the onside recovery. Unfortunately, reports indicated that Taiwan Jones fractured his forearm and will be done for the season.
A fracture is quite simple in terms of injury severity. A bone is broken at some point in the structure leading to instability and significant pain. Jones did not sustain a fracture which protruded through the skin which allows for the management to be more conservative. He will possibly require surgery depending on the severity and complexity of the fracture. He could hypothetically come back if they pushed recovery, but it is a bigger bone compared to what Jordan Matthews and Ramon Humber sustained and would require extra stability. Had this been McCoy or Taylor, it may be considered to push for a return. While Jones is an important part of the team, he is not what drives the offense. Placing him on IR will allow the Bills to bring in a new player to gain experience to provide depth and try out for next year.
As the Bills have an extended break between games, this allows these injuries to have a greater chance to get healthy with the exception of Taiwan Jones. As I’ve said before, no NFL team is immune from injury. The Bills are doing incredibly well with avoiding serious injury. However, despite that luck, the Bills still have to win those games that are winnable to turn things around for long term success. Going into the Saints game, while their offense continues to be high powered, their defense is suspect and will be playing at New Era Stadium which will provide a favorable atmosphere for the Bills to go 5-0 at home.

It has been reported that TE Charles Clay and CB E.J. Gaines should be returning from injury. It is surprising that Clay is able to return quicker than originally thought, but is a welcome addition. Gaines returning will provide an immediate upgrade to our secondary that without him, may be exploited by Drew Brees and the Saints.
