Amir, 34, has not played for Pakistan since the T20 World Cup in 2024 and qualified for a British passport via his wife, who is a UK citizen. He has joined Notts for the second half of the Blast’s group stage and will also be available for any potential knockout fixtures.

He will not count as one of the club’s two overseas players and will therefore be able to feature alongside both South Africa allrounder George Linde and Pakistan fast bowler Mohammad Ali. Notts sit second in the North Group after six group matches and expect to have Amir available for their away fixture against Kent on Friday night.

Cricinfo has learned that Amir is also a potential target for Trent Rockets in the Hundred, with David Payne (ankle) facing a race against time in his return to fitness after surgery. Another Rockets seamer, Matt Henry, has also emerged as a doubt after he was ruled out of the deciding Test against England with a low-grade calf strain.

“I’m really excited to have joined Notts,” Amir said. “I’ve heard lots of good things about this club, and I’m looking forward to it. I have lots and lots of memories at Trent Bridge, and I know that T20 is all about entertaining the people, so I’ll be trying my best to do well for this team and make this crowd happy.”

Peter Moores, Nottinghamshire’s head coach, has previously worked with Amir in the PSL with Karachi Kings. “Mo has a great skillset for both the Powerplay and the end of the innings, as well as the mental strength to deliver under pressure, which has made him so valuable to teams around the world,” Moores said.

Amir has previously featured in the Blast for Essex, Gloucestershire and Derbyshire, and has also played for London Spirit, Oval Invincibles (now MI London) and Northern Superchargers (now Sunrisers Leeds) in the Hundred.

He has signed as a replacement for AM Ghazanfar, who has been pulled out of his stint by the Afghanistan Cricket Board to manage his workload.
