Grimsby are set to complete the paperwork to sign former Coventry and Rotherham keeper Gary Montgomery. Montgomery, 24, was released by the Millmoor outfit at the end of last season and will move to Blundell Park on a free transfer.
Boss Alan Buckley told Mariners' website: "I have agreed terms with Gary and we're just waiting for him to put pen to paper.
"It's all sorted, it's just a matter of paperwork now, I'm pleased to get him."
