Liverpool captain Steven Gerrard has apologised after being sent off after just 38 seconds in the 2-1 defeat by Manchester United.
Gerrard, who joins LA Galaxy at the end of the season, will miss three games.
"I need to accept it; the decision was right," Gerrard told Sky Sports. "I've let down my team-mates and the fans."
He added: "I take full responsibility. I don't know what caused it. Probably just a reaction to the initial tackle.
"I shouldn't say more about it really. I've just come out here to apologise to the dressing room and supporters."
Having just returned from injury, Gerrard is now likely to miss FA Cup quarter-final replay against Blackburn, and two of eight remaining Premier League games - at Arsenal and at home to Newcastle.
The former England captain announced in January he was leaving Anfield at the end of the season, after joining the Reds aged nine.
"From now until the last kick of the last game of the season, I will be as fully committed to the team as I ever have been and giving everything I have to help Liverpool win games," he said at the time.
Gerrard, who made his Liverpool debut in 1998, led the club to the Champions League title in 2005, and has won a further nine trophies in his career.
