Oli McBurnie is unlikely to play any part in Swansea City's FA Cup quarter-final clash with Manchester City on Saturday (5.20pm).
The 22-year-old striker has missed the games against Norwich and West Brom due to the latest bout of illness he has suffered with in 2019.
Swansea's top scorer was able to take part in some light training on Friday, but manager Graham Potter does not expect him to play any part against Pep Guardiola's men.
"Oli is still missing, he will do some light training but it is a big percentage that he will not be available," he said.
"It is a real outside chance just because he has had such a long time ill, and not too much training.
"We will see how he is, he has just been really unlucky and picked up a sickness bug that has taken its toll on him.
"He has had blood tests and other tests and it is nothing sinister, he has just been really unfortunate. He has had a tough time."
Swansea are also waiting on the fitness of full-back Kyle Naughton after the defender felt some discomfort in his groin in the defeat at West Brom, while Cameron Carter-Vickers is set to shake off a knock to feature.
"We have a few bumps and bruises from the game against West Brom," added Potter.
"We are waiting on Kyle Naughton a bit. He just felt a bit in his groin area, it could just be fatigue but with such a short time to the game we need to give him more time before making a decision.
"Cameron Carter-Vickers had a knock as well but should be okay, apart from that we should have the same squad as we did at West Brom."
