The 22-year-old defender (pictured) confirmed that he is to leave the club he has been with all his career.
"I'm gutted to be leaving the club and I didn't want to go this way," Butterfield told the Grimsby Telegraph.
"The manager wants me to sign and said if any money comes his way he definitely wants me to stay with Grimsby, but it doesn't look like that's going to happen.
"He's done the professional thing and spoken to me and I've got the utmost respect for him, Graham Rodger, Paul Wilkinson and all the players.
"But there hasn't been any type of negotiations whatsoever and I'm not one of those players asking for ridiculous money - I haven't even had the chance to talk!
Bradley Allen has also confirmed that he will be leaving the club this summer, whilst there is also doubts over the future of Wayne Burnett, Ben Chapman, Simon Ford, Mickey Boulding.
