Wayne Rooney will be out for two or three weeks with minor ligament damage to his right ankle, Manchester United manager Alex Ferguson has said.
United's manager also reassured England fans saying the striker should be fit for the World Cup.
Rooney was injured in the last minutes of United's 2-1 Champions League defeat at Bayern Munich on Tuesday.
He's scored 34 goals for Manchester United this season, so fans have been really worried about the injury.
He'll miss the Premier League match against Chelsea on Saturday, the second leg against Munich on Wednesday and the following Sunday's league match against Blackburn.
Wayne Rooney could be back in two weeks
But he could be back for the Manchester City derby on April 17.
Sir Alex Ferguson said: "The nation can stop praying. It was panic. We are relieved. When we saw him hobble off, you are hoping when you send him for a scan you get some good news, and it could have been worse given the way he hobbled off."
