Chelsea's John Mikel Obi has been given a three-match ban and fined £60,000 by the Football Association for threatening referee Mark Clattenburg.
Mikel admitted an FA charge following an incident in the match officials' changing room after Chelsea's defeat by Manchester United on 28 October.
The FA accepted the player had believed the referee had racially abused him.
"But for that factor the suspension would have been significantly longer," the FA said in a statement.
In a personal hearing on Thursday the FA's Independent Regulatory Commission also accepted the Nigerian midfielder's explanation.
The FA has investigated the allegation against Clattenburg and found that there was no case for him to answer.
The police also dropped their own inquiry into the allegations that Clattenburg had racially abused Mikel, 25.
Mikel's team-mate Ramires had made the allegation and Chelsea later said they regretted the way the matter was handled.
Clattenburg missed four weekends of Premier League matches while the FA investigated Chelsea's complaint.
