A further recurrence of Darren Gough's knee injury has made him doubtful for the NatWest triangular one-day series against India and Sri Lanka.

England's premier fast bowler played in the City Challenge tournament at Edgbaston last Friday, and for Yorkshire's Academy the following day. However he was unable to play in the Second XI Trophy game against Nottinghamshire yesterday.

"It is the same knee problem as before and it looks as if it is back to square one for him," Yorkshire captain Darren Lehmann told the Yorkshire Post.

Gough tore a cartilage in his right knee during the final one-day international in New Zealand, and has twice undergone surgery, missing England's 2-0 Test series win over Sri Lanka.

Gough's regular new-ball partner for England in recent years, Andrew Caddick, has already been ruled out of the NatWest Series with a side strain.
