A thigh injury saw the defender limp off during his side's 4-0 destruction of Portugal and he could miss Saturday's meeting with the Black Stars, but Jerome Boateng is fit to playMats Hummels has been confirmed as a doubt for Germany's game against Ghana, while Jerome Boateng has suffered a ligament rupture in in his right thumb.
The Borussia Dortmund defender headed in his side's second goal as they trounced Portugal 4-0 on Monday, but his day was soured when he was forced to limp off 17 minutes from time with a thigh problem. In the first half, Boateng fell on his hand but was able to play through until the end of the game.
The two were sent for MRI scans on Tuesday and it was revealed Hummels has suffered a bruise in his right thigh and could miss out on Saturday's meeting with the Black Stars, but a decision will be made closer to the game.
"The injury doesn't feel like something which would end my World Cup," Hummels told Sport1 after the game on Monday.
"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."
Boateng, however, will be forced to wear a splint for the next six weeks and, depending on referee permission, will be able to play on Saturday.
