Cesc Fabregas has had his three-match ban reduced to just one after Chelsea successfully argued the initial punishment was excessive.
The Spain midfielder was sent off in Monday's 3-0 defeat at West Brom after kicking the ball against Chris Brunt's head during a break in play.
He will now only miss Sunday's final Barclays Premier League game against Sunderland, when champions Chelsea will lift the Barclays Premier League trophy.
A statement from Chelsea read: "The standard sanction would have been a three-match suspension.
"However, following an Independent Regulatory Commission hearing earlier today, the club's claim that a three-match suspension is excessive was successful.
"Fabregas will therefore now only miss our final game of the season against Sunderland on Sunday and will be available for selection from the start of the 2015/16 campaign."
Fabregas was dismissed in the first half of Chelsea's defeat at The Hawthorns after hitting Brunt on the head from 20 yards while referee Mike Jones spoke to Gareth McAuley and Diego Costa after they grappled in the area.
A statement from the Football Association read: "A claim by Chelsea that the three-match suspension for Cesc Fabregas is excessive has been upheld by an Independent Regulatory Commission hearing.
"Fabregas was dismissed for violent conduct during the West Bromwich Albion FC v Chelsea FC fixture on 18 May. The Regulatory Commission has reduced the Chelsea midfielder's suspension to one match, to be served with immediate effect."
Chelsea manager Jose Mourinho questioned the dismissal after the game and called it "bizarre".
He said: "Where is the danger of the situation, where is the aggression in the situation to get the red card in a friendly game?
"I really don't understand. I think (Darren) Fletcher was aggressive, he pushed him (Fabregas) in the chest because he is experienced and knows where he can push for a yellow card. He is much more aggressive than what Fabregas did.
"For me a top referee, a stable, big personality and in control of the game, goes there, two or three words and it's done. It's a bizarre red card.
"A three game ban for this? Harsh? Of course it's harsh. Why does he have to explain? He doesn't need to explain."
