DARREN Lehmann has had a scan on his stiff back and should know later today if he will be fit to play for Yorkshire tomorrow in their Championship encounter with Derbyshire at Derby.

The Australian left-hander has been considerably restricted by his sore back over the past few days and he was rested from Sunday's game against Somerset Sabres at Scarborough.

Yorkshire's director of cricket, David Byas, said: "We don't think that Darren has got a serious problem but because it has gone on for some time now it was felt it would be wise for him to have a scan."

The stiffness in Lehmann's back may be the result of the extensive travel he has done over the past few months. Since arriving at Headingley just before the start of the season, he has travelled to Zimbabwe as well as returning home for Australia's two Test matches against Sri Lanka.

Lehmann is on the team sheet for tomorrow's match but if he has to pull out his place will be taken by Vic Craven.

Definitely missing will be Chris Silverwood, who has had an injection on a sore heel which started to bother him last Thursday, and into the squad of 12 come pacemen John Blain and Nick Thornicroft.

Off-spinner Andy Gray is also included, leg-spinner Mark Lawson being unavailable because he is playing for England under-19s in their first Test against Bangladesh under-19s which starts at Headingley tomorrow.

Although Byas is still upset at the way Yorkshire capsized in their Championship match with Somerset last week, he has been heartened by the way they played against the same team on Sunday in the totesport League at North Marine Road.

"It was good to win on the back of some excellent batting by our home grown players for a change instead of having to rely on someone from overseas," said Byas.

"Matthew Wood is in really good form at the moment and I was delighted with the way Michael Lumb and Andrew Gale scored their runs."
