Looks like protective bracing on Phillips L elbow. Would assist in preventing elbow hyperextension & stress through inner elbow. As a DT, he is falling to the ground a variety of ways & getting arms pulled & pushed. Can’t find any previous elbow injury, may be precaution. #Bills https://t.co/LOULoYO5b5
