Manchester City defender Micah Richards is expected to miss the club's FA Cup semi-final clash with Manchester United after scans revealed he has a grade two hamstring tear.
Richards, 22, lasted just five minutes of England Under-21s' 4-0 win in Denmark last Thursday, pulling up sharply and requiring a stretcher to take him off the field.
Under-21s boss Stuart Pearce revealed after the match that Richards feared a long lay-off and hospital scan confirmed that he has suffered a tear that will keep him out for four to six weeks.
"It is not what I wanted to hear at all," Richards said. "I felt sick when I was told. I knew from experience when I did it that it felt like a bad one but I was hoping for the best.
"All I can do now is concentrate on getting back as quickly as possible. I must admit I did think 'why me?' for a while when I heard the news.
"Of all the games to miss a Wembley date with United is the last one any player would choose."
Richards plans to have an oxygen tent in his house in a bid to speed his recovery.
