The Football Association has begun an investigation into the incident that saw Brighton striker Ashley Barnes sent off after he appeared to trip referee Nigel Miller at Bolton.
Barnes was dismissed in the latter stages of the Seagulls' 1-0 defeat at the Reebok Stadium on Saturday.
Having already been sent off once this season, in last month's loss to Sheffield Wednesday, the 23-year-old is due to serve a four-match ban, but that could now be extended.
Speaking after the match, Brighton boss Gus Poyet had said he had been unaware of what had happened.
"I'm desperate to jump on the bus to see the DVD and to talk to Ashley Barnes," Poyet said.
"My way of managing this is I prefer the player to calm down, because if you go to the dressing room and you ask them straight away then they will put their excuse in there and blame somebody else.
"I'm going to say I suppose it was for talking [dissent]. I don't know. I cannot confirm because I have not talked to him yet. I saw nothing, I was looking at the ball."
When it was suggested that Barnes may have tripped Miller, Poyet replied: "I would like to see it. Now it's easier - now before I talk to him I'm going to have a look because if he's done something to the referee...
"Let's wait and see. It is difficult to have an opinion when you don't know what happened."
