Rushden & Diamonds have released six players but secured the future of midfielder Curtis Woodhouse. Dave Savage, Gary Mills, Chris Beardsley, Jason Goodliffe, Danny Williams and Scott Tynan have not been offered new deals by boss Garry Hill.
But Woodhouse has signed for two years after resuming his football career following a spell in pro boxing.
Woodhouse, 27, has scored three times in 14 appearances in two separate spells with Rushden.
