Chairman Stephen Vaughan said they had already listed Lee Steele and Sean Hessey to help reduce the wage bill.
"We've already placed Lee and Sean on the transfer list," chairman Stephen Vaughan told the club website.

"It could well be that we have to discuss this situation with the player, medical advisors and the PFA."
