Cincinnati Bengals wide receiver A.J. Green returned to practice Thursday after sitting out Wednesday due to a concussion.

Green suffered the injury in the fourth quarter of a 27-17 loss at Pittsburgh on Sunday night. Green was hurt on a hit delivered by Steelers cornerback cornerback Antwon Blake and moments later by safety Mike Mitchell.

He was alreadly playing with a deep biceps bruise that coach Marvin Lewis said could be limiting Green, who had eight catches against the Steelers.

Tight end Jermaine Gresham (back) did not practice Wednesday but is also expected to play Sunday against the Indianapolis Colts.

Green led the Bengals with 69 receptions for 1,041 yards and six touchdows but missed part or all of four games with a toe injury.

Green has 11 catches for 123 yards and two touchdowns in two career games against the Colts. He has 13 catches for 161 yards and no touchdowns in three career playoff appearances.
