Brown made 129 first-class appearances for Northants
Former Northants off-spinner Jason Brown has signed for Nottinghamshire on a two year-deal.
The 34-year-old, who was released by Northants in September, took 414 first-class wickets during his 14-year career at Wantage Road.
He told the club website: "There's going to be scope for me to play some good cricket at Notts.
"I bowled a lot with Graeme Swann at Northants and we seemed to compliment each other."
Brown added: "I'm pleased that he is getting opportunities with England and I can step in for Notts whenever he is unavailable."
We expect Graeme Swann and Samit Patel to be involved with England next year and that will provide opportunities for Jason
Nottinghamshire director of cricket Mick Newell said: "We expect Graeme and Samit Patel to be involved with England next year and that will provide opportunities for Jason.
"He's an experienced player and there is a possibility we'll deploy three spinners at times in one-day formats."
Brown made his first-class debut for Northants against Yorkshire in 1996.
He was selected for England to tour Sri Lanka in 2001, but only played in one warm-up game.
Notts recently lost the services of fellow spinner Rob Ferley, who rejected a new deal at Trent Bridge and has since rejoined Kent.
