West Ham's Daniel Gabbidon has been fined and warned about his future conduct following comments he made on social networking website Twitter.
The 31-year-old was charged with improper conduct for comments made after the 2-1 home defeat by Aston Villa on 16 April.
"Having admitted the charge, Gabbidon was fined £6,000," read a Football Association statement.
The Welsh international defender has since closed down his account.
He posted the message - which included swearing - in the wake of the defeat at Upton Park, where Gabriel Agbonlahor scored an injury time winner to keep West Ham deep in relegation trouble.
Gabbidon ended his final Twitter entry by writing: "U know what.... u will never get another tweet from me again, you just don't get it do you. Bye bye."
His FA charge came just after team-mate Carlton Cole was fined for comments made on Twitter.
The striker was sanctioned by the FA for comments he made about Ghana fans during their friendly against England.
He was also charged with improper conduct and fined £20,000, as well as being warned about his future conduct.
In January, Dutch winger Ryan Babel was fined £10,000 and warned about his future conduct by the FA over a post he made on Twitter.
