Warwickshire hope that Ireland pair William Porterfield and Boyd Rankin will be available to start next week’s County Championship match against Durham at Edgbaston.
Warwickshire expected to be without the pair for the match, which starts on May 24, as they will be required to travel to Belfast on Thursday to prepare for Ireland’s one-day internationals against Pakistan on May 28 and 30.
But they have now discovered that counties are entitled to use substitutes for players from Ireland, Scotland and the Netherlands under a new release agreement which will operate on similar lines to the existing regulation for England international players.
Players from the three associate member countries can be substituted provided they are available to play in 50 per cent of a County Championship match.
Warwickshire now intend to select opening batsman Porterfield, Ireland’s captain, and pace bowler Rankin and nominate two players who will replace them after the second day against Durham.
Warwickshire are certain to be without England pair Ian Bell and Jonathan Trott against Durham but they expect captain Jim Troughton to return.
Troughton has missed the last three Championship matches because of a shoulder injury but he is in line to play in the Clydesdale Bank 40 match against Durham at Edgbaston on May 22.
A decision on whether Bell and Trott will play in the one-day contest has yet to be taken. Bell opted to play in the CB40 match at Northampton two weeks ago and would have played at Leicester on May 15 but for a minor hip injury.
Trott was given the option of playing in both of those matches but he decided to take time off instead.
