Durham spinners Nathan Sowter and George Drissell have signed new contracts.
Australian Sowter, 31, has signed a new two-year deal, while Drissell, 24, has extended his stay with the club until the end of the 2024 season.
Former Middlesex leg-spinner Sowter spent time on loan at Chester-le-Street in 2022 before signing a one-year deal last December.
He took a club-record 24 wickets in last season's T20 Blast.
Off-spinner Drissell joined Durham from Somerset in 2021.
"I am excited to extend my deal with Durham, I have loved every minute of my time with the club so far," Sowter told the club website.
"With ambitions to keep improving in all formats across the club, it was a no brainer to commit for another two years. I can't wait to be a part of the club as we continue to progress."
