Warwickshire will be without West Indies batsman Shivnarine Chanderpaul for their County Championship match against Sussex at Edgbaston which starts on July 20.
Warwickshire have signed Chanderpaul as a replacement for former Pakistan batsman Mohammad Yousuf, their overseas player for the first half of the Championship season.
Chanderpaul, who has previous county experience with Durham and Lancashire, was expected to arrive in time to face Sussex but he has had difficulty in obtaining a visa in time.
Having travelled to Jamaica in a failed bid to obtain the necessary paperwork, Chanderpaul will now make a trip to the United States this week. Warwickshire hope that he will have obtained a visa before their Championship match against Lancashire which starts at Liverpool on August 1.
Warwickshire also face the prospect of being without Darren Maddy for the rest of the season after he suffered a broken left little finger against Lancashire last week.
The injury has proved to be worse than expected and Maddy underwent surgery. The initial prediction that he would be sidelined for between four to six weeks has now been revised to an absence of six to eight weeks, leaving Maddy battling to regain fitness before the end of the season.
Warwickshire hope that wicketkeeper Tim Ambrose will have recovered from a buttock muscle injury in time to face Sussex but he has been rested from the side for the Clydesdale Bank 40 match against Scotland in Edinburgh on Monday July 18 as a precaution.
Opening batsman Ian Westwood also has an ankle niggle but he is expected to be fit to face Sussex this week.
