Moses Odubajo will undergo a scan after being withdrawn because of a calf injury during QPR 1-0 win over Derby.
The full-back hobbled off the field shortly before the hour mark to be replaced by Osman Kakay.
Yoann Barbet, meanwhile, missed the game due to the same knee problem which kept him out against Preston prior to starting against Huddersfield.
“It’s a calf problem so we’ll see how he (Odubajo) is,” manager Mark Warburton said.
“A calf might be seven to 10 days or it might be 10 to 12 days. We don’t know. He’ll get it scanned and see how it is.
“Two games in three days was too quick for Yoann. Had it been two days’ time he’d have been fit because the inflammation would have gone down.
“It’s inflammation and when you have the games coming thick and fast, it just flares up and it needs time to calm down.
“He’ll play a game, go with the medical team to get it back into shape, get the inflammation down, and he can come and play.”
Lee Wallace and Jeff Hendrick also missed Monday’s game because of hamstring problems but Warburton is hopeful that Wallace could return in time for Saturday’s trip to Stoke City.
Warburton said: “Lee still felt his hamstring and Jeff was the same. Lee in a couple of days’ time maybe will be available but again, you just can’t risk it.
“We’ve lost too many players to injury, long-term injury, surgery, this season. Whether it be goalkeepers, wing-backs, whatever it may be. We’ve lost too many players.”
