David Pleat is waiting for reports to discover the extent of an injury sustained by Simon Davies on Welsh duty last night.
The midfielder was taken to hospital in Cardiff after limping out of the action in the first half at the Millennium Stadium.
Simon suffered a leg injury as he attempted a shot on goal in Wales' 4-0 win.
Acting boss David said this morning: "We're waiting for reports of X-rays on an injury he sustained in the early part in the game. That's all we can say for now."
Wales boss Mark Hughes reported last night: "Simon got a bang on the leg. It's quite swollen at the moment but he's gone to hospital and we'll see."
