London, July 15 - England coach Andy Flower is optimistic that his key all-rounder Andrew Flintoff will be ready in time for the second Ashes Test starting Thursday at Lord's.

Flintoff's right knee, operated recently, ballooned during the first Test against Australia in Cardiff. The English cricketer Monday met his surgeon, who gave some injection after which Flintoff had a short batting session at the nets Tuesday.

Flower said that Flintoff will undergo a fitness test on the eve of the match after his fitness will be assessed.

'His surgeon who operated on his knee was quite optimistic about him playing in this game. The suggestion is that he'll be okay but we can only make that decision later,' Flower was quoted as saying in The Daily Telegraph.
