Soccer: Manchester United's hopes of overturning Darren Fletcher's red card have been dashed after Uefa confirmed that a protest against a sending off would only be allowed on the basis on mistaken identity - and not on whether the referee had been too harsh.

Uefa head of communications Rob Faulkner said: "Manchester United have the right to file a protest within 24 hours of the match however a protest against a caution or sending off is only admissible if the referee's error was to mistake the identity of the player."

The decision means Fletcher will be suspended for the Champions League final in Rome later this month.

United boss Alex Ferguson had hoped referee Roberto Rosetti would have admitted it was a mistake to give Fletcher a straight red card for a foul on Arsenal skipper Cesc Fabregas in the box.

"He's one of the most honest players in the game and to miss the final, it's a tragedy," said Ferguson.

"In respect to the referee in this situation he might look at it himself without anyone asking him."

Although the Football Association have moved towards a position where referees regularly rescind red cards, both Uefa and Fifa strictly maintain the rules that match officials' decisions should remain sacrosanct.

A Uefa source added: "It opens Pandora's box if you can challenge every decision. And if you rule that it is not a red card, then you are also saying it is not a penalty, and therefore not a goal, and what do you do then - start changing the results of matches afterwards?"

Arsenal manager Arsene Wenger also admitted the red card was "very harsh" after television pictures clearly showed Scottish international Fletcher - a non-playing substitute at last year's final - played the ball.

Fletcher's case will be passed on to Uefa's disciplinary committee but only to confirm his statutory one-match ban.

The body does not review referees' decisions apart from to apply any sanction imposed on a different player in cases of mistaken identity.

Paul Scholes may be able to offer some words of consolation to Fletcher - he and Roy Keane suffered a similar fate in 1999.
