Richard Butcher rejoined Lincoln in July after his release by Notts County
Lincoln City could be without three key midfielders for Saturday's home match against Burton Albion at Sincil Bank.
Captain Scott Kerr went off at half-time in Tuesday's win at Bradford with a recurrence of a back problem.
Richard Butcher missed the game with a knee injury while Stefan Oakes suffered a foot wound which required stitches.
Manager Peter Jackson told BBC Radio Lincolnshire: "We'll assess them but it could be as late as Saturday that I can name my side to face Burton."
The Imps could also go into the game without striker Paul Connor (thigh strain) and full-backs Cian Hughton, who picked up a knock at Valley Parade and Joe Heath who missed the match with a hip injury.
Jackson said: "I've always said you have to be lucky with suspensions and injuries and we've got a lot at the moment.
"I could have six players missing at the weekend but that could open the door for some of the youngsters at the club."
