Swansea City defender Chico Flores is "very unlikely" to be fit for the Capital One Cup final later this month, after tests confirmed he ruptured ligaments in his right ankle during the win over QPR.
The Spaniard was stretchered off after 34 minutes yesterday, and taken to hospital, where a scan confirmed the injury.
"It's difficult at the moment to assess how long he will be out, because we need the swelling to go down first", Swansea's head physio Kate Rees said. "But he is very unlikely to make the cup final."
Chico travelled with the rest of the squad to Dubai this morning for a break, and will receive treatment from the club's medical stuff there.

Swansea City boss Michael Laudrup says this Saturday's match against the Premier League's lowest-ranked side QPR is crucial.
“It’s a very important game,” he said. “Not because they are bottom of the table, but because it is a home game and we want to win it. “We are still six points away from the magic 40 that everyone talks about, so we have some work to do.
“But we have two games before we play the cup final and Saturday is one that I feel we have to win – it’s a huge game.”
Laudrup says he is no hurry to sign an extension to his contract at the club, which is due to expire at the end of next season.
"I think for me the present is more important than the future, we have so many things coming up now and I already have a contract for next season so it is not urgent for me" he said.
"We have some very important things to deal with right now. I am talking to the chairman a lot of times every week and we talk about a lot of things."
