Deeks, who is in his second spell with the club, has been an almost-ever-present this season and has been a key part of manager Jamie Godbold's plans.
“I’m happy to be signing a contract for a couple of years. I feel it’s an exciting time with the club due to all the transition going on,” Deeks said. “I believe now is the right time for me to sign a deal and get this club stable at this level. I want to say a big thank you to the fans for their support this season. They have been awesome and made me very welcome to be back.”
