Fast bowler Zak Chappell will join Derbyshire at the end of the season, upon the expiry of his current contract with Nottinghamshire.
The 25-year-old joined the Green and Golds ahead of the 2019 season and has since gone on to make 18 all format appearances for the club, taking 28 wickets.
He remains available for Nottinghamshire selection and recently featured in the opening fixture of the club's Royal London Cup campaign against Sussex.
"Our bowling attack has certainly been competitive to break into for this past couple of years and that, combined with picking up some injuries at key times, has limited Zak's opportunities to play first team cricket,” said Nottinghamshire Head Coach Peter Moores.
“He wants to be playing regularly across all formats. Hopefully this move gives him an opportunity to do that, and it keeps him close to his roots in the East Midlands, so we completely understand and respect his decision.
“His attitude around the group has been positive throughout his time at Trent Bridge. He trains hard, has gone about his periods of injury rehab professionally and has handled his decision to leave in a respectful and positive way.
“There’s lots to play for and plenty we can still achieve during the remainder of the season – and I know Zak will be giving it everything.
“Once we get to the end of September, it will be a case of thanking him for his efforts and wishing him well for the next part of his career.”
