John Gregory has launched a clear-out at Crawley Town by releasing 11 players.
Defender Paul Connolly, who was recently banned for five matches after an altercation with a Brentford fan, heads the list of out-of-contract stars not offered new deals.
Strikers Billy Clarke and Rory Fallon, goalkeeper Paul Jones and popular winger Sergio Torres will also move on along with Mark Connolly, Gary Dicker, Louis John, Johnny Maddison, Alex Malins and Jonte Smith.
But Town boss Gregory has offered new deals to Dannie Bulman, Mike Jones, Jamie Proctor and Mat Sadler.
He told the club website: " Telling players they haven't been offered a new contract is one of the hardest aspects of management and it does not get any easier over time, believe me.
"We will have a competitive playing budget for next season but unfortunately some of the players who have been part of the journey this club has been on for the last few years will not be with us. I need to reinvigorate and refresh the squad.
"On behalf of the club and the supporters, I would like to express my thanks to those players who are leaving us for their service to Crawley Town FC and wish them all the best for their futures.
"The job of re-shaping the squad and the backroom team for next season is under way.
"There will be new faces and I'm sure our fans will be as supportive of them as they have of the players who have served this football club so well in the past."
