Matt Nicholson, the Australian fast bowler, will deputise for Mohammad Asif at Surrey for the first half of the season - and possibly the entire summer.

Nicholson took 44 wickets for Surrey last season in the Championship, but with uncertainty over Asif's involvement, he could play a fuller role than was first anticipated. Asif, the Pakistan fast bowler, will be unavailable until June at the earliest, and his board have also expressed concerns about his workload.

"The Pakistan board have said they are not going to allow their quick bowlers to play county cricket, which is understandable as most of their first-choice bowlers are on the sidelines at the moment," Alan Butcher, the Surrey manager, said.

"So while we have a contract, it must be said it's far from certain that he'll be able to take up that contract. At the end of last season Matt made it very plain that he'd be delighted to come back and play for us, and I know that everyone in the dressing room is really delighted he will be with us for at least the first part of the season.

"I would have no qualms at all if it turned into a full season's contract."
