Swansea City will not appeal against the red cards given to Kyle Bartley and Gylfi Sigurdsson during Saturday's 3-1 FA Cup defeat at Bolton.
Iceland international Sigurdsson will miss the next three games after being dismissed for violent contuct.
Defender Bartley's offence was the less serious professional foul which carries a one-match penalty.
He will miss the match at Southampton, while Sigurdsson is also ruled out the games against Sunderland and West Brom.
Garry Monk's team have received eight red cards during the 2014-15 season - more than any other team in the Premier League.
"Gylfi's one was disappointing. You can't react like that. But I don't think it was a red card," said Monk.
"I think a yellow would have been sufficient there."
