has admitted he was wrong to swear into a TV camera.
After starring in Manchester United's Champions League triumph over Chelsea on Tuesday night, Rooney must now sit out Saturday's FA Cup semi-final clash with Manchester City.
It is the second - and by far the most high-profile - part of a two-match suspension imposed by the Football Association for an unprompted four-letter reaction to scoring a hat-trick in the 4-2 win at West Ham.
Although Rooney has previously made it clear he feels victimised for the punishment, the 25-year-old, who was helping turn around a two-goal deficit into what is likely to become one of the pivotal days in the Premier League title battle, accepts his conduct was unacceptable.
"I didn't realise what I'd done," Rooney told talkSPORT. "It was just emotions. It was a release of scoring the three goals to get us back in the game. As soon as I realised after the game I apologised as soon as I could.
"Of course it was wrong of me to do but I accept my punishment and you just have to move on. Hopefully the boys can pull through for me on Saturday and hopefully get to that FA Cup final."
