Sunderland midfielder Sebastian Larsson has had an appeal against his red card versus Manchester United rejected by the Football Association.
The 31-year-old was sent off by referee Craig Pawson in the first half of the 3-0 Premier League loss to Jose Mourinho's side after a challenge on United's Ander Herrera.
Manager David Moyes was frustrated with the decision and Sunderland promptly appealed, but the FA has upheld the decision.
"An Independent Regulatory Commission has rejected a wrongful dismissal claim from Sunderland's Sebastian Larsson," it said in a statement.
"The midfielder was dismissed for serious foul play during the Black Cats' Premier League fixture against Manchester United on 9 April 2017.
"Larsson's three-match suspension remains in place."
The 31-year-old will miss league meetings with West Ham, Arsenal and Middlesbrough.
The news comes as a further blow to Sunderland, who are 10 points adrift of safety with just seven games remaining.
