Le'Veon Bell, RB, Pittsburgh Steelers.
Le'Veon Bell, RB (head/neck)
Bell went down at the end of the Steelers' contest with the Ravens Thursday night. He appeared to lose consciousness after a helmet-to-helmet hit knocked his helmet from his head. His neck hyperextended soon thereafter when he contacted the ground.
Fortunately, he rose to his feet after only a brief moment—obviously stunned but walking with only some assistance.
The announcement of a concussion diagnosis is a formality at this point. A cervical spine sprain—similar to whiplash in this case—is also possible.
Bell likely underwent or will undergo X-rays or CT scans of his cervical vertebrae shortly after the injury. An MRI may follow, after which he must start his own concussion return protocol over the coming days. The existence of any other soft tissue, bone or ligament injury may complicate his recovery.
That said, given how it initially looked, the NFL community can breathe a sigh of relief.
Brett Keisel, DE (foot)
Keisel left Thanksgiving's action with a foot injury, the details of which remain scarce.
According to 970 ESPN Pittsburgh's David Todd, the injury did not involve contact and occurred when Keisel pushed off the ground. Such an injury mechanism sometimes suggests an Achilles tear, but no reports of such an injury yet exist.
The Steelers lineman recently suffered from plantar fasciitis. His recent setback may constitute an aggravation of the injury or the completion of a partially torn plantar fascia. Details should come soon.
Emmanuel Sanders, WR (no significant injury)
Sanders fell with most of his weight on his left shoulder early on Thursday evening. He remained on his knees for some time before missing minimal time.
The Steelers wideout likely only had the wind knocked out of him. Falling hard on one's side can apply significant pressure to the abdomen, causing the diaphragm to briefly go into spasm.
A spastic diaphragm makes breathing quite difficult. Usually, it resolves within a few seconds to a minute or two—as it did in this case.
Fernando Velasco, C (unclear leg injury)
Velasco went down late with an unclear injury. TV cameras caught him requiring assistance to leave the field.
Mark Kaboly of the Pittsburgh Tribune-Review later tweeted the center required a walking boot after the game.
Depending on suspicions, medical staffs use walking boots to protect and immobilize the foot and ankle. An ankle sprain or fracture is possible, but the precise nature of the injury is not yet known.
