Atlanta Falcons backup quarterback AJ McCarron is out for the season with a torn ACL in his right knee, a source confirmed to ESPN on Sunday.
McCarron injured the knee in the second quarter of Saturday's 37-17 preseason loss to Miami. He grabbed his knee after handing the ball off to running back Qadree Ollison. As he completed his typical post-handoff movement, McCarron clutched the knee.
He tried to make it to the sidelines, but trainers and doctors examined him first on the field and then on the sidelines before he made his way to the locker room.
