The union urged the governing body of European football to show leniency after three players from each side picked up their third bookings of the competition and were therefore suspended for the final in Munich on May 19.
FIFPro pointed to the ruling at this summer's European Championships where Uefa will waive existing yellow cards from the quarter-finals onwards as an inconsistency.

Whilst Uefa have confirmed that they are not against the idea of changing the rules for future Champions League competitions, they also stated that there was no way in which they could be changed in the build-up to the final as any provisions that were in place when this year's tournament commenced must be continued.
It is also believed that any changes to the current system would need to go through a tricky and potentially lengthy committee process.
"The regulations of the competition are established at the beginning of the competition and remain in place for the duration of the season," a Uefa spokesman told the Press Association.
"Any changes to the regulations for the future would need to be proposed by the club competitions committee and approved by the UEFA executive committee."
Bayern will be without Holger Badstuber, David Alaba and Luiz Gustavo whilst the Blues must deal with the absences of Branislav Ivanovic, Raul Meireles and Ramires for the final on May 19.
