Mario Gomez is also likely to play again in the lone striker role, while squad captain Bastian Schweinsteiger is pushing for a start.
Slovakia defender Dusan Svento and midfielder Robert Mak have been battling muscle injuries.
Peter Pekarik took a heavy blow to the nose against England but is fit.
Coming into the tournament, a popular school of thought was that Germany's potent array of attackers would have to be at the top of their game to outscore their opponents, given their defence had been unusually porous in recent times.
However, it has been the opposite so far. In their last two matches Joachim Low's side have scored with only one of 44 shots and they managed a grand total of just three goals in the group stage. But, at the other end of the pitch, their defence has looked impregnable - admittedly in the face of some less than razor-sharp attacking.
The last goals they conceded were actually against last 16 opponents Slovakia. The Slovaks pulled off an excellent 3-1 win against an experimental German team less than a month ago which was played out in monsoon conditions in Augsburg.
Slovakia took huge confidence from that victory, but they know things will be very different this time around. "They'll be more focused," Slovakia coach Jan Kozak said. "They are the world champions and won their group without conceding a goal, that says it all. It's a typical tournament team. They know how to play big tournaments. They are aware that Euro 2016 begins for them only with the game against us."
Slovakia impressed in Group B by beating Russia and battling to a goalless draw with England. They know how to frustrate the big teams and are very happy playing in a defensive style if necessary.
