Fulham midfielder Bryan Ruiz will have a scan to determine the extent of an ankle injury picked up in the stalemate with West Bromwich Albion.
The Cost Rica international was carried off moments before Gareth McAuley headed in an injury-time equaliser to cancel out Steve Sidwell’s opener at Craven Cottage.
Ruiz looked in considerable pain as he went down on the halfway line under the challenge of Liam Ridgewell and Fulham are now sweating on the fitness of the forward.
Whites boss Martin Jol said:”[Bryan] Ruiz’s [injury] looks quite serious so we have to scan him and wait and see what the problem is.
“It is with his ankle. I have no idea of the severity of it but we will see.
Bulgarian striker Dimitar Berbatov, who had two goals chalked off for offside, was also withdrawn but Jol is more is more optimistic over the frontman’s fitness.
He added: “Berbatov had a hamstring [problem]. I don’t think that is serious. He gave us signal that he wanted to be substituted and hopefully it was just in time.”
