The global football players' union says UEFA has rejected its appeal for six suspended Bayern Munich and Chelsea players to be allowed to play in the Champions League final.
Bayern's David Alaba, Holger Badstuber and Luiz Gustavo, and Chelsea's Branislav Ivanovic, Raul Meireles and Ramires are serving one-match UEFA bans for their third bookings in the competition.
FIFPro says it is "disproportionate" that players should miss the final in Munich on May 19 after receiving a yellow card in the semifinals.
But FIFPro says "UEFA states the rule will stay in force for the coming three years."
A yellow-card amnesty rule already applies after the quarterfinals stage in UEFA's European Championship and FIFA's World Cup.
