Swansea City manager Graham Potter has revealed that the trio of Oli McBurrnie, Wayne Routledge and Declan John are being monitored by the club's medical staff and a decision on their availability for the Leeds United trip will be made just ahead of the game on Wednesday.
Striker McBurrnie came off the bench in the 70th minute of the match against Millwall despite being troubled by injuries in recent weeks.
Winger Routledge has a problem with his calf and though he took part in the match against the Lions, he remains an uncertainty against the Whites.
Full-back John on the other hand was forced to leave the pitch after receiving a knock in Saturday's match.
"Oli has just had a period where he has picked up a few things, so we just have to be careful with him and monitor him", Potter said at a press conference.
"He trained lightly yesterday, so we will see how he goes.
"I think it was tough for him to come on, but we will make a decision for Leeds closer to the time.
"Declan is 50-50, he had that contact on his ankle so I am not sure if he can make it, let's see.
"Wayne felt a bit of fatigue in his calf, we just want to monitor him because he has had issues with that over the last few weeks."
Skipper Leroy Fer is certain to miss the match though as he continues with his recovery from a hamstring injury.
Joe Rodon and Martin Olsson are the other significant absentees.
