Northamptonshire have confirmed they are searching for an overseas replacement for the T20 Blast after Australian all-rounder Ashton Agar was ruled out with injury.

Agar had been booked to reprise his 2024 role at Wantage Road for the domestic T20 competition which starts on 29 May.

But the 31-year-old confirmed he will not now return after suffering a calf strain.

“I’m extremely disappointed to be missing this year’s Vitality Blast with Northamptonshire,” said the left-arm off spinner.

“I loved my time there last season, it’s a fantastic club with great people and I’ll be watching and supporting the boys from Perth.”

The Steelbacks, who have won the Blast twice, made it out of the group stages last season before losing to Somerset in the quarter-finals.

Agar played six matches, topping their batting averages and taking four wickets.
