Cincinnati Bengals wide receiver A.J. Green did not practice Friday after being on the field on a limited basis Thursday.

Green, who was scheduled to visit an independent neuropsychologist on Friday, was seen at practice in sweats.

The Bengals’ biggest receiving threat is in league-mandated concussion protocol and his status remains uncertain for Sunday’s wild-card game against the Indianapolis Colts.

Green is not allowed to talk to the media until he is medically cleared and likely will be limited again in practice Friday.

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

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

Green leads the Bengals with 69 receptions for 1,041 yards and six touchdowns 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.
