England pace bowler James Anderson is confident Andrew Flintoff will be fit to face Australia in next week's third Ashes Test at Edgbaston.
Flintoff produced a man-of-the-match display at Lord's as England took a 1-0 lead in the five-match series earlier this week.
But the all-rounder was troubled by a knee injury, which has already forced him to announce he will retire from Test cricket after the Ashes, and there is a doubt over his fitness for the Edgbaston clash.
Anderson knows Flintoff better than most after also playing with him at Lancashire for several years and he told BBC Radio Five Live: "Obviously Fred performed fantastically well this week with a knee injury and if he is able to bowl 90mph with this injury I think he'll play.
"But it's obviously down to Fred, if he thinks he can get through the three Tests we have got left.
"If he thinks it is maybe going to put him out of the last two he may miss the next one, but we have got a week's rest now so hopefully he can put his feet up and be fit for a week on Thursday."
Anderson was also one of England's most impressive performers with the ball at Lord's, although it was his role as a batsman in the first Test draw at Cardiff that ensured England went into the game level.
"We did fantastically well at Cardiff to get anything out of the game," Anderson added. "We didn't want to waste the good work we did at Cardiff by not performing well at Lord's.
"I think it probably spurred us on, the draw at Cardiff. We are obviously in a fantastic position in the series now and hopefully we can kick on."
Anderson has also insisted he and Monty Panesar did not indulge in time-wasting during their heroic last-wicket partnership in the Cardiff draw.
Twelfth man Bilal Shafayat twice came onto the field between overs towards the end of the game and was accompanied by the physio on one occasion.
"There was a lot confusion," Anderson said. "The 12th man did actually spill some drink on my glove and had to come out again.
"The physio thought I was calling for him and came out as well.
"The Australians are obviously going to think I was time-wasting but it was all pretty innocent."
