A.J. Green took a step toward playing in Sunday's playoff game at Indianapolis.
The Pro Bowl wide receiver dressed for practice Thursday for the first time this week and did warm up work with his teammates, but did not participate in full practice.
Per NFL concussion guidelines, Green will see a neuropsychologist on Friday and would have to be cleared by an independent neurologist on Saturday to be able to play in Sunday's game.
Green suffered a concussion in the Bengals loss at Pittsburgh.
The Bengals play the Colts in the first round of the playoffs at Lucas Oil Stadium.
