Sky Bet League Two leaders Luton will be without suspended defender Jack Stacey for the visit of Grimsby.
Stacey begins a three-match ban after being shown a straight red card during last weekend's victory at Forest Green.
James Justin is in contention to replace Stacey against the Mariners, but captain Scott Cuthbert (groin) and Irish defender Alan McCormack (hernia) remain out.
Striker James Collins and midfielder Harry Cornick are pushing for their first starts since returning from recent injuries.
Grimsby midfielder James Berrett could make his return to action at Luton.
Berrett has had a couple of false starts on his way back to fitness but made the bench last weekend and is travelling south with the squad.
Scott Vernon and Jonathan Hooper are options up front but manager Russell Slade is unlikely to over-commit against the league leaders.
Experienced defender Paul Dixon provides another option should Slade prefer to stiffen his back line but has not started since November 11.
