McKnight reportedly fell to the field during a drill on Monday, before being carted off. That came after he dropped to a knee three times on his way to the field. McKnight was examined by trainers prior to practice and poured water over his head before jogging off. Jets head coach Rex Ryan said McKnight would not have been on the field had there been any concern about his condition.
"For whatever reason, he stopped or whatever and that's fine," Ryan said. "There's no chance any player would be on the field if the trainers or doctors felt that it wasn't safe for that person to be there."
According to the report, McKnight went down during practice after diving for a pass. Trainers examined him for a few minutes, looking at his leg, before taking him off in a cart. McKnight has had issues with migraines before during his career, including lat last season.
The Jets didn't provide a further update on McKnight's condition, although he did return to the sidelines wearing street clothes and dark sunglasses to watch the end of practice.
