Swansea City have injury concerns over Federico Fernandez and Kyle Bartley ahead of their weekend clash with Chelsea.
The Swans will look to take another step towards Premier League survival when they face last season’s champions at the Liberty Stadium on Saturday (5.30pm).
But boss Carlos Carvalhal must wait to see whether two of his central defensive options will be available.
Regular team captain Fernandez picked up a knee problem when he slid in on Raheem Sterling during last weekend’s loss at Manchester City.
The Argentine left the field as a result and was replaced by Bartley, who then complained of pain in his knee.
“We have situations with two players who are having scans this afternoon – Federico Fernandez and Kyle Bartley,” Carvalhal said.
“We don’t know about them yet. We have good expectations but we must be sure when we see the scans.
“Federico got a kick on his knee. He felt some pain. We don’t think anything is damaged but we must see.
“Kyle is also the knee – I think he has stretched the internal ligaments. Sometimes players have pain but it is nothing mechanical and they can play, so let’s see.”
Should both Fernandez and Bartley miss the Chelsea game, Carvalhal will have only two fit centre-backs in Alfie Mawson and Mike van der Hoorn.
But Kyle Naughton started in a back three last time out at home, against Everton, while the likes of Angel Rangel and Connor Roberts are also fit and available.
Luciano Narsingh, meantime, is being assessed after missing the Manchester City game with an ankle problem.
