Lincoln boss Steve Tilson hopes Clark Keltie will be fit for the visit of relegation rivals Cheltenham.
However, Mustapha Carayol is unlikely to play again this season after suffering a recurrence of a hamstring injury against Bury on Friday.
Keltie was a late omission from the side that lost at Gigg Lane after the midfielder sustained an ankle injury in training. Winger Carayol, meanwhile, broke down on his return from injury as a second-half substitute.
"Clark had to drop out after we had done all of our patterns of play and Mussie has pulled his hamstring again," said Tilson. "We are not getting too much luck at the moment, but we must put all of our efforts into Monday now.
"I hope Clark will be fit enough, but with Mussie, I think it will be very doubtful if he plays again this season. All week he was been fine, yet he comes into a game and suffers the same injury."
Tilson will be boosted by the return from suspension of 17-goal leading scorer Ashley Grimes, while defender Adam Watts could also be fit again after illness.
Cheltenham boss Mark Yates will keep faith with Wes Thomas ahead of the encounter.
The striker spurned a host of chances during the 1-0 defeat to Macclesfield at the weekend which kept the Robins in relegation trouble.
Yates said: "Wes Thomas has scored 19 goals this season and while he didn't have his best game, he has been a revelation here.
"He now needs to be a revelation for another three games."
Winger Josh Low returned on Saturday after missing three matches with a leg injury and, after lasting 78 minutes at Whaddon Road, should be available to start again.
However, striker Jeff Goulding and right-back Keith Lowe continue to miss out with their respective ankle injuries.
