New Zealand’s Hamish Rutherford will be available to play for Worcestershire in the T20 Blast when the delayed 2020 county season starts on 1 August.
But plans for Australian all-rounder Ashton Turner to link up with the team for the tournament have been shelved.
Turner is needed by Western Australia.
“Because of the change from the original T20 dates, Ashton would not be available for the entire competition,” said Worcestershire cricket steering group chairman Paul Pridgeon.
“He would be required to return for practice by his state side.”
Rutherford, who played a handful of matches in all three formats last summer and played for Worcestershire in their T20 final defeat by Essex, originally signed to play for the whole of the 2020 season.
But head coach Alex Gidman is looking to the left-hander, son of former New Zealand captain Ken Rutherford, to make an impact at the top of the order.
“It’s been a bitterly frustrating time for anyone in cricket all around the world and it’s no different for Hamish,” said Gidman.
“The T20 is something we’ve been successful in for the past two years and, regardless of how that competition looks this year, we want to try to do as well as possible in it.”
A start date for the 2020 domestic season has been announced but, as yet, there is no confirmation of how the amended schedule will look.
