Newport County will give goalkeeper Lenny Pidgeley a late fitness test ahead of the visit of Mansfield.
The former Chelsea keeper was handed his first start since November at the weekend but was stretchered off with 20 minutes to go with a calf injury and is rated as 50/50 for Tuesday's clash with the Stags.
The Exiles were leading 2-0 when Pidgeley was taken off, but could only manage a 2-2 draw with Tamworth.
It means they will slip out of the play-off places for the first time this season if they are beaten by sixth-placed Mansfield.
Striker Aaron O'Connor is sidelined with a thigh injury and is expected to be out for three to four weeks, while Max Porter is a couple of weeks away from a return from his groin problem.
Mansfield are unlikely to make any changes as they look for a fifth successive victory.
The Stags made just one change from the side that beat Dartford 5-0, Louis Briscoe starting in place of Lindon Meikle, as Paul Cox's side thrashed Barrow 8-1.
The result earned Cox a new car from the club's chairman and he is not expected to tinker with his line-up as his side look to break into the play-off places.
Injured duo Ross Dyer and Jake Speight (both knee) remain the only absentees in the squad.
Speight scored twice in the reverse fixture, as the Exiles ran out 4-3 winners on the opening day of the campaign.
The Stags have tightened up at the back since. In their last four outings they have conceded only three goals and found the net 18 times.
