Warwickshire are facing an anxious wait to discover the extent of captain Jim Troughton’s shoulder injury.
Troughton landed awkwardly attempting to take a catch in Scotland’s run chase during the CB40 match against Scotland at Edgbaston on May 2.
Although Troughton suffered no obvious discomfort at the time his shoulder seized up overnight and prevented him from sleeping.
Warwickshire sent him for scans the following day and are still waiting for the results.
But they may be forced to revise their plans for the Championship match against Lancashire at Edgbaston, starting on May 4.
Opener Ian Westwood, Troughton’s immediate predecessor as captain, and Ireland captain William Porterfield were due to be left out to accommodate the availability of England pair Ian Bell and Jonathan Trott.
But Westwood and Porterfield are expected to remain at Edgbaston to cover for Troughton as part of extended squad.
Warwickshire have included rookie offspinner Maurice Holmes, who made his competitive debut against Leicestershire in the CB40 match on May 1, for a possible first Championship appearance.
Slow left-armer Paul Best, who replaced the injured Ant Botha in last week’s defeat by Durham, is back at Cambridge University.
Fellow left-armer Chris Metters, who bowled well on the pre-season tour to Barbados, is regaining fitness and form in the second team.
