The France international suffered a ligament strain in his left ankle during his side's 3-2 win over Fortuna Dusseldorf on Saturday.
Bayern are also sweating on the fitness of Arjen Robben, who was not involved at the weekend because of a calf problem.
Bayern hold a 3-1 lead from the away leg, though, to put themselves in pole position for a place in the quarter-finals.
