Denmark goalkeeper Thomas Sorensen could miss the World Cup after injuring his elbow during Stoke's 7-0 loss at Chelsea in the Premier League on Sunday.
The injury comes 50 days before Denmark's World Cup opener against the Netherlands on June 14 at Soccer City in Johannesburg.
"He has definitely dislocated his elbow," Stoke manager Tony Pulis said. "They are hoping they can just pop it back in and he doesn't have to have an operation. If he has to have an operation, then he's struggling for the World Cup."
Sorensen was hurt when Salomon Kalou scored from close range. Kalou slid to score and appeared to catch Sorensen after the goalkeeper had parried a shot from Frank Lampard in the 31st minute.
Sorensen received oxygen as he was carried off.
He was replaced by former Canadian under-20 goalie Asmir Begovic, who now plays internationally for Bosnia.
