Bayern Munich winger Franck Ribery is a doubt for Tuesday's Champions League semifinal against Atletico Madrid due to a back injury.

Bayern coach Pep Guardiola says ''he's injured'' but adds ''we'll do everything we can so that Franck is there.''

Bayern lost the first leg 1-0 in Madrid.

Ribery missed Bayern's 1-1 draw at home with Borussia Moenchengladbach on Saturday, a result that put the side's Bundesliga title celebrations on hold.

Xabi Alonso and Javi Martinez were left out of the squad for a rest, while Philipp Lahm, David Alaba, Arturo Vidal, Thiago Alcantara, Douglas Costa and Robert Lewandowski were all on the bench. Alaba and Thiago made substitute appearances.
