Regarding his injuries, Channing was recently examined by doctor James Andrews, who had this to say about Channing's knees."Both knees are stable at this time with no evidence of any degenerative changes. There is no reason this young man cannot continue to play football, even at the highest level, with the current status of his knees. I feel confident the patient is not at any increased risk of having additional ACL tears."
