Shane Warne has voluntarily taken a full blood screen in Australia in a bid to clear his name.

Warne was sent home after failing a dope test and faces a two-year ban if his B sample also proves positive.

But Rod Bransgrove, chairman of the leg-spinner's English county side Hampshire, said Warne is taking matters into his own hands.

The results of that screening will not be known for another week, but Warne still hopes he can play a part in Australia's World Cup campaign.

Newspaper reports said Warne's mother "badgered" the bowler into taking a diuretic tablet which led to him failing the drugs test.

They claimed Warne's mother, Brigitte, often complained about his appearance and urged him to take one of her tablets prior to an appearance on television.

An unnamed family friend said: "She badgered him and he said 'For Christ's sake just give me the tablet' and never thought anything of it."

The International Cricket Council has condemned India players whose personal sponsors continue to advertise in violation of World Cup rules.

India had signed contracts which prohibited them from advertising for non-official sponsors for the duration of the tournament.

The agreement put to bed a long-running dispute that had threatened India's participation in cricket's showpiece event.

But the row returned on Friday, with the ICC accusing electronics giants Samsung of ambush marketing by issuing advertisements in newspapers.

ICC chief executive Malcolm Speed said: "There is clearly documented evidence that Samsung is deliberately and blatantly flouting the contractual agreements that exist with the Board of Control for Cricket in India."

"This is a pre-meditated campaign designed to infringe and devalue the rights secured by the ICC's commercial partners."

Pakistan wicketkeeper Rashid Latif announced his retirement from international cricket following a 10-year career.

The 34-year-old, who will play his final one-day match at the 2003 World Cup, said he will continue at domestic level, but thought it was time he handed over the gloves to someone else.

He announced his retirement from Test cricket in November last year and hinted at calling it a day altogether after one last try at World Cup glory.

A vital South Africa practice session was called off after several batsmen were struck on dangerous net surfaces at The Wanderers.

Jacques Kallis and Andrew Hall both suffered worrying knocks as batsmen struggled to cope with unpredictable bounce.

No injuries were reported, but it disrupted South Africa's preparations for their World Cup clash against New Zealand at the Johannesburg ground on Sunday.

"I think everyone got hit at least once," coach Eric Simons said.

"From a bowling perspective it was alright but, from a batter's point of view it was not easy to get your confidence.

"Guys like Gary Kirsten and Herschelle Gibbs who have confidence can easily lose it. It isn't ideal when guys need to walk out of the nets, it's a pity but we did get some work done."

Bangladesh captain Khaled Mashud pointed the finger at his batsmen for the second match in a row after his side were humbled by Sri Lanka.

The match was effectively over after the first over as Bangladesh slumped to five for four following a Chaminda Vaas hat-trick.

In their first match, the Tigers were turned over by Canada after another batting collapse.

"We made early mistakes like the last game against Canada," Mashud said.

"We are capable of doing better than this, but the batting is just not working. Vaas was very good, but we could not build a partnership after those early strikes."

Fears over the fitness of England's Craig White escalated on Friday when coach Duncan Fletcher admitted there was no suitable replacement for the seam bowling all rounder.

He will bowl in the nets at Buffalo Park in East London on Saturday where his progress will be monitored.

Scans have confirmed that White, who picked up the injury in the fourth Ashes test, has not suffered a muscle tear but there is still a problem with his left side which restricts his bowling.

"The x-ray shows there is nothing there at the moment but we will look at him again," said Fletcher. "There is probably some scar tissue in there but we want to see him bowl again and then look at the situation.

"We have got to think of the balance of the side," Fletcher added. "It will be difficult to replace him with like for like as I don't think there is anyone around like that to replace him. His bowling is important and the guys have got to be pretty fit in one-day cricket."

The Australian Cricket Board on Friday applied to the International Cricket Council to confirm whether it can replace Shane Warne at the World Cup "if needed".

"We are seeking confirmation of our understanding that we are able to replace Shane if needed. A replacement player has not yet been finalised as this is pending results of final Australian Sports Drug Agency (ASDA) testing of Shane's B sample," ACB Chief Executive Officer James Sutherland said.

He said ICC has advised that the application will be considered by the World Cup Technical Committee at the earliest, may be by Friday afternoon.

"But we have applied for the technical committee's confirmation so that we can later move more quickly to select and have a replacement approved, if needed," he said.
