Manchester United will face no further action over their conduct at Stamford Bridge on Sunday.
After picking up seven yellow cards during the draw with Chelsea, Sir Alex Ferguson's men already knew they would receive an automatic £25,000 fine from the FA.
However, there was a fear referee Mike Riley might suggest further incidents needed looking at, particularly Rio Ferdinand's challenge on Didier Drogba at the end of the game and the aggressive attitude of some Red Devils players after the final whistle. Those worries have now been allayed, with Riley confirming in his match report that he was happy with his handling of various incidents, meaning the Red Devils will avoid further scrutiny.
Although clearly unhappy with some of Riley's decisions, Sir Alex Ferguson's wisdom in keeping his own counsel has also been proven.
Ferguson did claim there had not been a bad tackle in the game, although he resisted the obvious temptation to condemn Riley.
"It was a competitive game but I did not think there was one bad tackle in it," said the United boss.
"The game is being screened worldwide. Everyone is watching it and something like that happens.
"People are saying what is going on here but it is difficult to say anything about the referee.
"I do not want to get involved."
