Lee Tomlin has signed a new contract keeping him at the club until the summer of 2022.
Tomlin, 30, has scored four goals and providing five assists in 18 appearances.
"I'm absolutely buzzing to get it done and dusted," said Tomlin.
"The fans stuck by me, no matter what and I'm starting to repay them.
"I think that's why I had no intention of going anywhere else, because for me they've been unbelievable.
"Every time I start a game and you go out at home it brings a smile and a shiver down my spine. I just want to do well for them as well."
