The Atletico Madrid and England defender was in December handed a 10-week suspension after advising a friend by text message to “lump on” his move to from Tottenham in 2019.
Atletico appealed against the suspension but football’s world governing body announced on Monday it had been dismissed.
“The Fifa appeal committee has dismissed the appeal lodged by the club Atletico Madrid in a case concerning the player Kieran Trippier,” a statement read.
“As a consequence, the decision of the Fifa disciplinary committee passed on December 23, 2020 is confirmed, extending sanctions imposed on the player by the English FA to have worldwide effect.”
However, the FA failed in its attempt to revise the dates of Trippier’s ban, which would mean if the club now appealed to the Court of Arbitration for Sport he would be free to continue playing.
The FA had wanted to revise the effective dates of the ban, which ends on February 28, but its own independent regulatory commission has dismissed the application.
Trippier was found guilty of four of the seven charges against him. He featured in Atletico’s LaLiga match against Sevilla on January 12.
