Bayern Munich coach Jupp Heynckes expects Germany defender Mats Hummels to start Wednesday's German Cup tie at RB Leipzig despite suffering an ankle injury at the weekend.

"Mats took a knock to the bone, only microfibres have been damaged, which doesn't mean much," revealed Heynckes in Tuesday's press conference.

"The injury isn't so bad that he can't play from the start. He will be treated further, but I assume he'll start."

Hummels' inclusion in the squad is good news for Bayern after stand-in captain Thomas Mueller was ruled out for the next three weeks with a torn hamstring which he suffered in Saturday's 1-0 win at Hamburg.

Stars Manuel Neuer, Juan Bernat and Franck Ribery are already sidelined long-term with injury.

Alongside Hummels, Kingsley Coman, who picked up a knee knock at Hamburg, and Javi Martinez, back after a shoulder injury, are included
