DURHAM have stood by their plans to leave Andrew Pratt and Danny Law out of their one-day side for today's C & G Trophy fourth round tie against Lancashire at Riverside.

Michael Gough has also been sent with the second team for the four-day match at Blackpool, where ironically they were key members of the side which played in the C & G quarter-final two years ago.

Law opened the batting and the bowling, Gough was third top scorer with 27 and bowled five overs, while Pratt brought off one of the best stumpings anyone in the Press tent could recall. Standing up to Law, he got rid of pinch-hitting opener Glen Chapple for 23, but Andrew Flintoff (72 not out) and Neil Fairbrother (73) set up a seven-wicket win for Lancashire.

As was planned for Sunday's washed out National League match against Derbyshire, Philip Mustard will make his senior one-day debut behind the stumps today and 21-year-old all-rounder Ian Pattison also comes in.

Nicky Peng and Mark Davies return after injury and Stephen Harmison is back from Test duty, although England will not allow him to play in the championship match against Yorkshire at Headingley, starting on Friday.

Skipper Jon Lewis explained that worried about the middle order batting had prompted the changes.

"We're quite happy with Andrew's wicketkeeping, but like everyone else we need runs from our keeper and we think he's good enough to get 800 a season," he said. "Going in in the middle order in a one-day match is not the best place to find form and it's much the same with Danny.

"With four-day games at Headingley and Hampshire coming up, both of which can be bowler-friendly, we need our top order batsmen in good form, so we are also hoping Michael Gough can benefit from four days at Blackpool."

With Vince Wells ruled out by a back injury, Mustard is likely to find himself well up the batting order, especially after his swashbuckling effort in the third round for the Durham Board X1 against Glamorgan. He also made 75 against Sri Lanka last year in his only first-class innings, and Lewis said: "He has shown some decent form this year and he is fearless. His natural game is to strike the ball as he sees it, and that's what we want him to do."

Gough's absence weakens the bowling options, and as Pattison is the only all-rounder it looks as though Durham will have to gamble on getting a full allocation of ten overs out of his medium pace.

Lancashire are without Andrew Flintoff, whose powerful hitting turned the National League game at Riverside three weeks ago.

They are also looking vulnerable after emulating Durham by losing to Scotland on Sunday, but they have the potential to make a big total with Stuart Law and Carl Hooper in their middle order.

Hooper has arrived as a stand-in for Harbajhan Singh until it becomes clear whether the Indian off-spinner can recover from injury in time to play a meaningful role.

Durham: J J B Lewis (capt), N Peng, G J Pratt, M L Love, G J Muchall, I Pattison, P Mustard, D Pretorius, N Killeen, N C Phillips, S J Harmison, A M Davies.
