On-loan defender Olly Lancashire is a doubt for Grimsby`s home clash against in-form Morecambe.
The centre-half was forced off after just 18 minutes of last weekend`s goalless draw at Shrewsbury with a hamstring problem.
Boss Neil Woods is confident he was able to replace Lancashire before any real damage was done but his chances of making a recovery ahead of Friday`s game are slim.
"I think we got him off in time. We`ll give it a chance to settle and try and manage it properly but it`s looking doubtful he`ll be ready," said Woods. "He had a problem with the hamstring in his other leg recently and we think it's more to do with a lower back problem."
Joe Widdowson`s return to fitness after a foot injury could prove timely. The defender, along with striker Nathan Jarman, travelled to Shrewsbury but were not included in the matchday squad.
Either Widdowson or Nicky Featherstone, Lancashire`s replacement at the New Meadow, will start should Lancashire miss out. Jarman could also be included after regaining fitness following a broken metatarsal.
Morecambe boss Sammy McIlroy will again name an unchanged side.
McIlroy has no new injury or suspension concerns but on-loan Huddersfield midfielder Ian Craney is still ruled out with an ankle injury.
However, the Shrimps were given a boost this week when fellow midfielder Manny Panther returned to full training.
Panther, on loan from Exeter, is making rapid progress in his recovery from a broken toe which has sidelined him since September.
He sustained the injury in a collision with Sol Campbell in the Shrimps' 1-0 win over Notts County in the defender`s only appearance for the Magpies.
Panther could now feature in the Lancashire Senior Cup tie against Preston on Monday.
