Haydn Hollis has joined Forest Green Rovers after having his Notts County contract terminated to facilitate his move to the New Lawn.
The 25-year-old, who progressed through the Magpies academy system before making his debut in 2012, made 137 appearances for the club and scored eight times.
However, Hollis slipped down the pecking order this season, being restricted to appearances in the EFL Cup and EFL Trophy, and has now opted to join Mark Cooper's League Two side to get first-team football.
Kevin Nolan told the official Notts site on Hollis's departure:"I would like to wish Haydn all the best in his new venture.
"Even though his first-team opportunities have been limited this season due to the fine form of Richard Duffy, Shaun Brisley and also Elliott Hewitt, his attitude in training and around the club has been first class.
"I'm confident he will go on to have an excellent end to the season and career. I'm gutted to lose him but it was in his best interests to move on and play football."
Hollis, meanwhile, said: "It was really hard for me to leave after nine great years but the time has come to move on in my career.
"I would like to take this opportunity to wish everyone connected with the club every success in the future."
