World Cup:Germany playmaker Bastian Schweinsteiger is facing a race against time to get fit for Sunday's last 16 match against England after picking up a thigh injury last night.
Assistant coach Hansi Flick confirmed this morning that time could be running out for the Bayern Munich midfielder.
"He has sustained a thigh injury. The doctors say time is running out but we hope he can play because he is an important player," Flick said.
Schweinsteiger has become a leading figure in the team since captain Michael Ballack was injured before the finals and his absence could be costly as Germany seek a quarter-final place.
He was injured late in the 1-0 win over Group D rivals Ghana that clinched top spot. Midfielder Toni Kroos could replace Schweinsteiger, though any decision would be taken closer to the game.
Flick said Jerome Boateng, who started against Ghana in place of left back Holger Badstuber, was also doubtful with a calf injury for the match in Bloemfontein.
Mesut Ozil, who scored the winner against Ghana, twisted his ankle but is fit to play against England.
