Rio Ferdinand could face a three-match ban for a bizarre challenge on Fernando Torres during Manchester United and Chelsea's FA Cup quarter-final draw.
Ferdinand ran up behind Torres and appeared to needlessly trip up the Spanish substitute as the duo jogged upfield.
After Torres was felled Ferdinand dismissively pulled him back to his feet, apparently unimpressed at the Chelsea striker's tumble.
Referee Howard Webb did not see the off-the-ball incident however ITV's eagle-eyed pitchside cameraman picked up the collision.
Goals from Javier Hernández and Wayne Rooney gave United a 2-0 lead at the interval but Eden Hazard and Ramires struck to earn Chelsea a deserved replay against a lacklustre Reds.
Ferdinand, who has never won the FA Cup, admitted United were complacent against the Blues.
"We gave them the impetus to claw their way back into the game," he told MUTV. "We played some great football at times but were so careless at times. If you are careless you are going to get punished. That was the case.
"But we are still in the cup. Wembley is waiting for one of us to go through and hopefully it is us.
"We go to Stamford Bridge for the replay with confidence. We have the tools. We have been there before this season and done well and with the squad we have we don't fear going anywhere."
