Celtic wing-back Didier Agathe has been ruled out of the crucial Champions League game in Lyon on December 10th.
He picked up a hamstring injury in the goalless draw with Bayern Munich last night and will be sidelined for up to six weeks.
Celtic manager Martin O'Neill is already without his left-sided midfielder Alan Thompson for the game in France after the England hopeful received a second caution in the competition.
Agathe's injury will gift Ireland's Liam Miller another opportunity to shine on the big stage. The young Corkman came off the bench last night but will relish the prospect of starting such a vital game.
Celtic need only a point against Lyon to become the first Scottish club to progress beyond the first group stage of the Champions League.
Agathe is now facing a race against time to be fit for the second Old Firm game of the season against Rangers at Parkhead on January 3rd next year.
