Bayern Munich will appeal against a three-match ban imposed on Franck Ribery, which has ruled him out of the Champions League final on 22 May.
The midfielder missed Tuesday's 3-0 win in the second leg of their semi-final against Lyon after he was sent off in the first tie in Germany.
Ribery, 27, was shown a straight red for a tackle on Lyon's Lisandro Lopez.
Bayern had hoped Uefa would restrict the Frenchman's ban to one game but are now pinning their hopes on an appeal.
But Bayern believe Uefa's control and disciplinary body's punishment is too severe.

"Uefa informed us of the decision, arguing that Franck Ribery was guilty of 'serious foul play'," read a Bayern statement.
"We do not understand this decision in any way and consider it absolutely wrong.
"Franck Ribery can certainly not be accused of violating his opponent intentionally. The player Lisandro Lopez was able to continue the game.
"Bayern and Franck Ribery will not accept the decision, but appeal and exhaust all possibilities."
The ban also covers Ribery for the first European match of next season.
The German side will play either Barcelona or Inter Milan in Madrid in the final in Madrid.
