Theo Walcott is a major doubt for England's decisive Euro 2012 Group D game against Ukraine on Tuesday after he picked up a knock in training.

The Arsenal man impressed when he came off the bench against Sweden on Friday by scoring one and setting up another, which give the Three Lions a 3-2 victory.

England boss Roy Hodgson has revealed that Walcott could well miss the game against Oleg Blokhin's men after pulling up in training.

"Unfortunately he had a slight setback in training," Hodgson said.

"He felt the hamstring that kept him out for so long at the end of the season and which we were slightly concerned about when he came to us," The Telegraph quote Hodgson as saying.

"We have been lucky nothing has occurred with that but in a little training session today we had to take the precaution of taking him from the field because he felt some tightness there.

"Whether he is a real contender for a starting position will depend upon what the medical people can tell me and how much guarantee they can give me that if I do start him he won't be leaving the field after five minutes, forcing us to have 13 men rather than the 14 I would rather count on," he confessed.
