Defender Jack Sparkes has completed a permanent move to Sky Bet League Two side Bristol Rovers.
The full-back, who joined Posh after a successful spell at Portsmouth, scored once in 28 appearances in all competitions for the club.
He finished last season on-loan at Sky Bet League Two side Chesterfield. Left-back Sparkes has put pen to paper on a two-year deal with the Pirates, after a free transfer with performance-related contingency fees was agreed between the two sides.
Best of luck Jack!
