Yorkshire have a great chance to end their slump in form tomorrow when they take on bottom-of-the-table Leicestershire Foxes at Grace Road in Division One of the National League.

But there was dismay among the players yesterday upon hearing that their new overseas signing, Yuvraj Singh, will not make his Yorkshire debut.

He was due to arrive yesterday but a hold-up in obtaining his visa means he is now expected to fly to England on Monday and the 21-year-old left-hander's first appearance is likely to be in the Championship match against Glamorgan at Headingley on Wednesday.

At least Yorkshire had some better news regarding Chris Silverwood, who is joining the squad after missing the current Championship match at Northampton with a painful right elbow.

Silverwood has had a pain-killing injection and he will have nets today and tomorrow morning to see if he is fit to play now, or whether he should wait a few days for the injection to kick in.

Phoenix have won one of their two National League matches so far but the Foxes have shocked even themselves by their poor start which leaves them pointless after three games.

If they lose to Leicestershire the knives will be out and director of cricket, Geoff Cope, and coach, Kevin Sharp, will then have to convince the fans that the slump can be quickly halted.

Yorkshire were spared further punishment at Northampton yesterday by persistent rain which ensured there was no play possible. With Northantson 311 for two and trailing by 88 on the first innings there seems little chance of forcing a result.

Yorkshire Phoenix (from): Wood, Lumb, McGrath, Craven, Blakey, Fellows, Bresnan, Gray, Silverwood, Dawson, Sidebottom, Hoggard, Kirby.
