Germany defender Nico Schlotterbeck has been ruled out of the rest of the World Cup with an ankle injury.
The 26-year-old left-footed centre-back suffered the problem in his side's 2-1 win against Ivory Coast on Saturday and was replaced by Antonio Rudiger at half-time.
A Germany national team statement said Schlotterbeck had "suffered an injury to the medial collateral ligament in his left ankle" and "will be out for several months".
It added that the Borussia Dortmund player would "remain with the team in the USA for the time being".
Germany, who have already secured top spot in Group E and their progress into the last 32 before they face Ecuador on Thursday (21:00 BST), cannot call up a replacement as the tournament has started.
