Borussia Dortmund defender Mats Hummels has been ruled out of the Germany squad for their upcoming World Cup qualifiers against Republic of Ireland and Sweden.

The 23-year-old picked up a hip injury in his club's 1-1 draw with Manchester City last week, but it is a separate foot injury that has ruled him out of the action.

Hummels has recently admitted a desire to leave Dortmund "one day" in search of pastures new.

The German has 22 international caps to his name.
