Tevez was fined four weeks' wages - believed to be around £800,000 - after the club found him guilty of misconduct during the Champions League match against Bayern Munich on September 27, when manager Roberto Mancini claimed the striker refused to play.
City had asked the PFA to ratify the fine, but PFA chief executive Gordon Taylor has backed the Argentinian after attending last week's hearing. A PFA statement read: "The PFA's opinion, based on all the evidence presented, is that Carlos Tevez never refused to play for the club.."
The statement continued: "This is accepted by the club in that the charge against Carlos made at the hearing was not one of refusing to play. As such the PFA considers that there is no justification for a fine other than up to the prescribed sanction of two weeks' wages agreed by the FA, the Premier League and PFA.
"The PFA has informed the Manchester City Football Club accordingly and Carlos will continue to be supported by the PFA in this regard."
