West Ham have appealed against the red card shown to Lee Bowyer in Saturday's Premier League clash at home to Birmingham.
Their case will now be heard at Soho Square at 1pm on Tuesday.
Boss Alan Curbishley said on Saturday: "We have asked Mark to look at it, and we think he will. Hopefully he will overturn it.
"When it happened I did not think it was that serious, but on the spot, the referee sees it differently.
"I think Johnson has come in and both of his feet have connected with the ball, so I don't know if Bowyer has gone above it. We will have to wait and see.
"If he is suspended, it is a bit tough and we could do with a suspension least of all with the injuries we have got."
