Sami Khedira and Mario Gomez are doubts for Germany's Euro 2016 semifinal against France or Iceland on Thursday after departing the penalty shootout victory over Italy injured.
Khedira exited after 16 minutes with a muscular injury following a collision with Italy defender and Juventus teammate Giorgio Chiellini, while Gomez was replaced in the 72nd minute with a similar knock but the signs for the 30-year-old striker are slightly more positive, according to Germany coach Joachim Low.
"It was not positive for Khedira to have to go off after 15 minutes. He has muscular problems in his thigh. I am not sure it will be working out for Thursday," Low said. "Mario Gomez also had muscular problems, but I think he came off early enough.
"It was clear we would need [substitute] Bastian Schweinsteiger over the course of the tournament. He did well, he worked hard and it was important to have his experience on the pitch.
"You need different players in such a tournament, it is not unusual for players to pick up injuries or suspensions. Mats Hummels is suspended for the next game."
Hummels was booked in the final minute for a foul on Eder, his second yellow of the tournament which earns him a one-match ban
Following the game the defender said: "The second yellow card is hurting, to be suspended because of those two situations. But my body can rest two or three more days."
Khedira, meanwhile, praised Germany's collective effort against the Azzurri after they restricted Antonio Conte's side to few chances.
"The Mannschaft has played like one big team. We didn't really allow them anything. We were very unlucky to concede," he told UEFA.com.
"Mario Gomez and I had to come off. We now have some ailing players, which is normal in such a big tournament. We will once more field a competitive side in the semifinal."
