(AP) - New York Jets running back Joe McKnight appears to be OK after dropping to his knees a number of times at training camp.
He was carted to the locker room, wearing an oxygen mask, after dropping to the field during a drill.
McKnight suffers from migraine headaches and has been recovering from a head injury. He took a knee three times as he made his way onto the field and was examined by trainers.
He returned to the field about an hour later to watch the end of practice.
