Coventry are in talks with trialist Steve Jennings as they look to tie up a deal for the midfielder.
Jennings, who rejected the chance to stay with Scottish club Motherwell this summer, has been trying to earn a deal with the Sky Blues for the past few weeks and featured in the second half of Saturday's 2-1 pre-season victory over Bristol Rovers.
The 27-year-old has impressed manager Andy Thorn, who told Coventry's official website: "I thought he did well at the weekend. Him and his agent are now in talks with the club at the moment."
He added: "I can't tell you any more about it at the moment but he has done well since coming here."
