Defenders Danny O'Donnell and Ashley Westwood will be surprise inclusions in the Crewe squad when Torquay visit Gresty Road.
Both players were forced off in the first half of the 2-1 home defeat to Bournemouth on Saturday.
However, O`Donnell is making good progress in his recovery from a dead leg, while tests have revealed Westwood only turned his ankle and suffered no ligament damage as initially feared.
"It`s a surprise but a good surprise to have both Danny and Ashley fit and available so soon," said caretaker manager Dario Gradi, who revealed he may "tweak" his side against the Gulls.
Midfielder Luke Murphy is the most likely to force his way into the team after impressing as a substitute against Bournemouth.
Defender Mat Mitchel-King (ankle) and midfielder James Bailey (abdominal strain) are expected to resume training this week but this game, and the trip to league leaders Rochdale at the weekend, will come too soon.
The game is subject to a pitch inspection that will be conducted by a local referee at 11.30 on Tuesday morning.
Torquay are boosted by the arrival of experienced centre-back Guy Branston, but Scott Rendell is out.
Branston, 31, has joined the Gulls on loan until the end of the season from League Two rivals Burton.
On-loan targetman Rendell is out after he broke an arm in the 2-1 home defeat by Bradford - the club's fourth defeat in five league games.
Boss Paul Buckle has snapped up Southampton's Trinidad & Tobago international winger Jake Thomson, 20, on loan until the end of the season.
Thomson has already spent a successful three-month loan spell at Torquay.
