CINCINNATI (AP) - All-Pro receiver A.J. Green twisted his left knee while trying to make a sideline catch during the Cincinnati Bengals' first practice of training camp on Thursday.
Green planted his left foot and and twisted the knee while reaching for the ball. He went down hard, rolled on his back and immediately grabbed the knee. After a trainer examined the knee, he got up and walked off the field without assistance to get treatment.
Coach Marvin Lewis said the injury doesn't appear to be serious.
Right tackle Andre Smith was back with the Bengals for the start of training camp, but couldn't practice because of an injured calf. He expects to practice on Sunday. Smith missed all of the offseason workouts and minicamp because of a personal issue.
