Manchester City defender Michael Ball has been charged with violent conduct by the Football Association.
The left-back stamped on Manchester United's Cristiano Ronaldo in the second minute of Saturday's Premiership clash.
City's official website, www.mcfc.co.uk, claim the Blues left back has until 6pm tomorrow to answer the charge.
United went on to win the game 1-0 with a penalty from Ronaldo.
But United manager Sir Alex Ferguson was left fuming at the incident, which referee Rob Styles did not punish.
The Old Trafford boss raced to the touchline to remonstrate with the officials after Styles, who was unsighted, waved play on.
