Craig White returns to action in place of the injured Michael Vaughan in Yorkshire's LV County Championship match against Division One bottom club Worcestershire at Headingley Carnegie tomorrow.

White made way for Vaughan at the Rose Bowl last week but the England captain's attempt to find form with Yorkshire for a few matches before the start of the Test series against the West Indies was scuppered when he broke his right middle finger while facing Australia paceman Stuart Clark.

Yorkshire have suffered a slight blip to their excellent early-season form over the past few days but they will be confident of doing well against Worcestershire, who have lost both of their opening two four-day matches.

White hit a century in Yorkshire's first game of the season against Surrey at The Oval but has done little since - and Anthony McGrath also needs to get a big score under his belt after an indifferent start.

The pair of them will be looking to turn in performances similar to when Yorkshire met Worcestershire at Headingley ten years ago and won by 66 runs to snuff out their opponents' chances of winning the title.

McGrath, opening the innings on that occasion with Vaughan, plundered 141 and White did even better, making an unbeaten 172 with 20 fours and seven sixes - five of them coming off Bradford-born left-arm spinner Richard Illingworth, now a first-class umpire.

This is Matthew Hoggard's fourth and final Championship game for Yorkshire before the Test series begins and another good performance should leave him razor-sharp for England.

In his three matches so far, Hoggard has claimed 12 wickets at an average of 19.05 runs apiece, his best effort being five for 32 in the win over Durham at Headingley.

Bradford has always had a strong link with Worcestershire, whose director of cricket is Steve Rhodes, the wicketkeeper-batsman who went to New Road after starting his career with Yorkshire.

Rhodes announced today that he had signed Scottish international Dewald Nel for a ten-day period because the club's bowling resources have been stretched by injuries to Australian left-arm fast bowler James Bollinger (side and hip strain), Matt Mason (shoulder) and Nadeem Malik.

Yorkshire have already met up with Nel once this season. He was in the Scottish Saltires team for the Friends Provident Trophy clash between the sides in Edinburgh and he claimed two wickets for 34 runs in ten accurate overs.

Worcestershire also include former Yorkshire left-hander Phil Jaques and the Australian has already been in good touch this season, with a Championship 97 against Durham and an FP Trophy century off Nottinghamshire's attack on Sunday.

Yorkshire: White, Sayers, McGrath, Rudolph, Younus Khan, Brophy, Rashid, Bresnan, Gough, Gillespie, Hoggard.
