If a complaint is made to the FA or referee Tony Leake includes the incident in his report, Morris could face a disrepute charge.
He returned to haunt his old club with a late equaliser from the penalty spot. Then he taunted home fans with an over-the-top goal celebration.
Leeds Supporters Club chairman Ray Fell said: "It wasn't helped by Morris running down the side of the pitch to the halfway line celebrating. I have seen players booked for looking at opposition fans."
