England all-rounder Craig White makes his first appearance of the season for Yorkshire at Bradford Park Avenue tomorrow in the three-day match against Bradford-Leeds Universities' Centre of Excellence.

White, who played in the Ashes series and the World Cup during the winter, had an operation just before the start of the season to remove two inches of bone from the lower part of a rib.

He made his comeback for Scarborough a week last Saturday, but for now will continue to play solely as a batsman.

Also in the side as Yorkshire try to pick up the pieces following three heavy defeats in eight days in three competitions, will be Gavin Hamilton, who has not played first team cricket for a year.

He has batted well with the seconds but Yorkshire need to know that he is back to his all-round best before they can consider him for a Championship match.

Matthew Wood will again captain Yorkshire in the absence on Test duty of Anthony McGrath, while Darlington-based wicketkeeper Simon Guy gets his first game of the season, although Richard Blakey retains his place as a batsman.

South African-born Pieter Swanepoel has a further chance to impress following his successful debut against Durham and left-arm pace bowler Ryan Sidebottom returns after a hamstring injury.

Vic Craven, the Harrogate-born left-hander, will be keen to continue the batting form he showed on Sunday, when he plundered a century for Pudsey Congs in their six-wicket win over East Bierley in the Bradford League.

Darren Gough, Chris Silverwood, Michael Lumb and Steve Kirby all take a rest before Sunday's National League game with Kent Spitfires at Tunbridge Wells.

Yorkshire coach Kevin Sharp will not be at Park Avenue tomorrow. Instead, he will be at Riverside for a scheduled two-hour meeting with England coach Duncan Fletcher to pick up some tips on coaching batsmen.

Sharp admitted that there was some soul-searching to be done by Yorkshire after their defeat by Durham.

"We have to learn to dig in and also take lessons from the way Jon Lewis batted," he said.
