Cholet's progression to the EuroChallenge Final Four on Wednesday night came at a cost with the team's electric point guard Nando De Colo suffering a broken nose.
De Colo, 21, had played less than six minutes when he suffered the injury.
Erman Kunter's team survived without the player, prevailing 80-74 over a gritty BC Kyiv outfit.
Cholet have announced in a statement on their website that De Colo will miss at least the next three games against Dijon (March 28), Orleans (April 4) and Hyeres-Toulon (April 11) and that his condition will be assessed again next week.
By advancing to the Final Four, Cholet will take on BC Triumph in the Semi-Finals.
Proteas EKA AEL will meet Virtus BolognaFiere in the other semi.
