MK Dons defender Mathias Doumbe will serve a four-match ban after the Football Association upheld the club's appeal against his dismissal at Leeds.
The Frenchman was shown a red card for a foul on Sanchez Watt during last weekend's 4-1 defeat at Elland Road and, having already been sent off before this season, he faces four games on the sidelines.
A Regulatory Commission dismissed the claim for wrongful dismissal, so Doumbe's season has come to an end and he will also miss the opening two matches next season.
Meanwhile, MK Dons stats skysports.com understands Millwall and Brighton are chasing MK Dons star Peter Leven.
Leven has impressed at MK Dons since joining the club in the summer of 2008 from Chesterfield.
