Bayern facing defensive headache after Hummels limps off at Hamburg


Bayern Munich could face Atletico Madrid without their first-choice pairing in central defence after Mats Hummels limped out of Saturday's Bundesliga game at Hamburg.

The Germany centre-back sustained a knock to his knee during a goalless first half at the Volksparkstadion and had to be withdrawn just eight minutes into the second half.

Jerome Boateng, himself on the comeback trail from injury, came on the replace Hummels.
