Durham Jets will be without top-scorer Calum MacLeod for tonight’s game against Yorkshire Vikings at Headingley.
MacLeod has scored 274 runs in the NatWest T20 Blast so far this season.
However, he is on international duty with Scotland and will miss out on the derby against neighbours Yorkshire.
Scotland play Netherlands in the second of three limited-overs games in Glasgow, which means MacLeod will be absent at Leeds.
Head coach Jon Lewis said: “It’s a blow for us because Calum has been in good form and has been our most consistent player in the competition so far.
“We always knew Scotland would have the first call on his services, so this has not come out of the blue.”
After being rested for the last two games, Chris Rushworth has been recalled to the squad, while Michael Richardson is also included.
Lewis added: “Chris is back in the squad but I haven’t decided yet whether to change the bowlers.
“It will depend on the situation with Ben Stokes and that’s down to England selection.”
The Jets are bidding to complete back-to-back T20 wins for the first time this season after their eight-wicket victory over struggling Derbyshire Falcons at the weekend.
They are currently sixth in the North Group with seven points from eight games, one point behind Yorkshire who are immediately above them but who have played one game fewer.
Lewis said: “This was always going to be a big week for us.
“With four games, it was a chance to really get cracking in this competition.
“The weather meant there was no result against Northamptonshire on Friday but then we had a good result against Derbyshire on Sunday.
“The important thing now is to build on that if we are to finish in the top four and make it to the next stage.”
