Is it a rotator cuff injury, an impingement, or simply tendonitis?

Do we actually have any answers to what’s bothering his shoulder? He was throwing fine in the game for the most part, but they handed the ball to Cook a lot. I’m fine with that since it was working, but it seemed like it was done to not have Josh throw.

Thank God we have a mini-BYE now before the Bengals. This rest should do him some good.
