Grimsby manager Mike Newell is hopeful of Peter Sweeney returning to Blundell Park.
Sweeney had an eight-game loan spell from Leeds at the end of the 2008/09 campaign.
"I've spoken to Sweens a few times and had a chat with him earlier this week, and he has not ruled anything out," Newell told the club's official website.
"Obviously midfield is a priority and Peter Sweeney is certainly a player we would like to bring in."
