Bengals receiver A.J. Green returned to practice Wednesday after a nearly three-week absence because of a bruised knee.

Green was allowed to participate in non-contact drills only. It's unclear whether he could play in Cincinnati's second preseason game Saturday night against Tennessee at Paul Brown Stadium. Green says he would like to play.

He bruised his left knee while trying to make a sideline catch during the first practice of training camp on July 25. He's been held out of practice since then, working on getting the knee healed.

Green says the knee is fine and he'll do a little more in practice each day leading up to the preseason game. The All-Pro receiver caught 97 passes for 1,350 yards and 11 touchdowns last season.
