Warwickshire have completed the signing of seam bowler Oliver Hannon-Dalby from Yorkshire.
The Halifax-born 23-year-old had been given permission to look for a new team by Yorkshire and has been training with the county champions in recent weeks.
Hannon-Dalby, who was entering the last year of his contract at Headingley, has played 24 first-class matches for Yorkshire, taking 43 wickets at an average of 45.06, with two five-wicket hauls.
Yorkshire director of cricket Martyn Moxon said: "As opportunities for Oliver to play first 11 cricket at Yorkshire this season are likely to be limited and given the fact that he was entering the final year of his contract, it was agreed that we would allow him to explore potential options elsewhere.
"With that in mind, he has spent the last few weeks training at Warwickshire and although I have some sadness that Oliver is leaving us, I am delighted that he is being given an opportunity to further his career.
"He has been a pleasure to work with and I would like to thank him for his contribution to the club. I wish him every success in the future."
