Joey Barton sufferes because of his sending off against Manchester City on the final day of the Premier League season.
The 29-year-old was hit with a 12-match ban and fined £75,000 by a Football Association-appointed independent regulatory commission last month after being dismissed for elbowing Carlos Tevez, then kicking out at Sergio Aguero as he left the pitch in the match on May 13 before aiming a headbutt in the direction of Vincent Kompany.
Joey Barton (on Twitter): "I was reckless and deserved every punishment I received.
"Money comes and goes, it's not important to me. Losing the captaincy and missing 12 games is what really hurts.
"I was stupid and that what happens when u [sic] do dumb things. I am confident ill [sic] bounce back. Cannot wait.
"That's all I have to say on the matter. I wish to put it behind me now and help QPR, once available of course, push on towards the top half.
"Have a good day people. Thanks for all the lovely tweets of support. Speak soon xx."
Chief executive Philip Beard: "It was important that we took our time to make sure we came to the correct decision, which I believe we have achieved.
"Joey's behaviour, which led to his red card at Manchester City, and his subsequent actions were completely unacceptable and we have made our feelings on this matter known to him.
"I am really pleased with the way in which the club and Joey have worked towards reaching a sensible conclusion and we fully believe he will respond to these sanctions in the correct manner."
