Alabama coach Nick Saban said receiver John Metchie "has an ACL and will be out" for the Cotton Bowl.
The Crimson Tide is scheduled to face Cincinnati on New Year's Eve in the national semifinal.
Metchie suffered the injury during Saturday's 41-24 win over Georgia in the SEC Championship Game. Saban discussed the injury Sunday on ESPN (via Charlie Potter of 247Sports):
"John Metchie's been an outstanding player for us, no doubt. He's a good leader. He's the leader of that group in a lot of ways. He has the most experience.
