Marlon King is likely to start Coventry's home clash against Doncaster.
The striker made an impressive contribution when he came off the bench to make his debut in Saturday's 2-1 reverse to Preston, inspiring a fightback which came close to snatching a deserved share of the spoils.
After the game, manager Aidy Boothroyd said: "He (Marlon) has given himself a good chance of starting on Tuesday. He's focused and very much looking forward to playing a key part in what we are doing here."
The Sky Blues boss may opt to make make or two changes elsewhere following Saturday's defeat, although he was anything but disappointed with his side's efforts as they dominated North End only to be thwarted by keeper Andy Lonergan.
Gary McSheffrey, Danny Ward, David Bell and Michael McIndoe are all pushing for starts, but the likes of Freddy Eastwood (knee), James McPake (shin) and Gary Deegan (ankle) remain in the stands.
Doncaster skipper Brian Stock is pushing for a recall to the starting line-up at Coventry.
Stock has been on the bench for the last two games after resting his back injury but he is now primed to return to the Rovers midfield.
James Hayter came off the bench in Saturday's 2-0 loss at leaders QPR after a lengthy absence with a hamstring injury, playing the final 10 minutes, and he could also be in contention to start.
But manager Sean O'Driscoll, who has no new injury or suspension worries, is unlikely to make too many more changes to his side, despite the heavy defeat in west London.
Rovers are chasing their second away win of the season and three points would see them continue to mix it in and around the play-off zone.
