Mats Hummels picked up an injury during Germany’s semi final clash against Brazil.
The 25-year-old Borussia Dortmund defender has been outstanding at World Cup 2014 so far, scoring two goals, and giving Joachim Low’s side an added stability at the back.
Hummels came off at half time with his team leading 5-0 against Brazil, and was replaced by Per Mertesacker. Germany would go on to accomplish an emphatic 7-1 win over World Cup hosts Brazil.
After the match, coach Low told ARD television that Hummels had “just taken a knock to the thigh,” and he doesn’t “expect it to be anything dramatic.”
However, Hummels told ARD that he has “problems with [his] knee.”
The center back will go for tests on Wednesday to ascertain the severity of his injury.
Hummels is optimistic about his chances of playing in the World Cup final on Sunday.
“The injury doesn’t feel like something which would end my World Cup,” Hummels told Sport1 television.
“Maybe it will cost me one game, or maybe none at all.
“It looked worse than it is. I do have my thigh heavily wrapped, but it’s going to be fine.
“It could have been worse,” Hummels concluded.
If Hummels does go out, Low could pair Jerome Boateng with either Mertesacker or Benedikt Howedes.
Should Low go with Howedes and Boateng, he could field Dortmund youngster Erik Durm at left back, or go with Kevin Grosskreutz at right back and shift Philipp Lahm over to left back.
