Chelsea have appealed against captain Marcel Desailly's three-match ban for elbowing Monaco's Fernando Morientes during their Champions League semi-final last Tuesday.
The appeal will be heard by European soccer's governing body UEFA on Friday and the result known before Chelsea's home leg with Monaco on May 5, the club said on their website.
The 35-year-old France captain's ban was based on video evidence as referee Urs Meier did not see the incident, during the match which Monaco won 3-1.
The London side said another Chelsea defender, Robert Huth, also faced a ban after the English FA requested video footage of a clash between the young German and striker Alan Shearer towards the end of a English premier league game last Sunday.
If Huth is found guilty any suspension would be served in domestic games only, the club said.
