West Ham have appealed against the red card shown to Lee Bowyer in Saturday's Barclays Premier League clash with Birmingham.
Referee Mark Clattenburg issued a straight red to the former Leeds midfielder for an alleged two-footed challenge on Blues captain Damien Johnson, two minutes from the end of the 1-1 draw at Upton Park.
Hammers manager Alan Curbishley revealed his unhappiness with Clattenburg's decision after the game and the London club lodged their appeal to the Football Association before today's noon deadline.
Their case will now be heard at Soho Square at 1pm tomorrow.
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.'
The FA have also confirmed that they will be studying television footage of Newcastle midfielder Joey Barton's clash with Aston Villa forward Shaun Maloney.
Barton appeared to lash out during the first half of his side's 4-1 defeat at Villa Park on Saturday but the incident was not spotted by referee Lee Mason at the time, and the official also made no reference to the incident in his post-match report.
The FA have, however, deemed that the issue is worthy of further investigation and their Football Regulation committee will look at the pictures, and ask for Mason's opinion on them, before deciding whether to charge Barton.
A spokesman told PA Sport that if Mason admits he would have taken action against the Newcastle player had he seen the clash, the FA are likely to pursue the matter further.
