Tottenham winger Gareth Bale will be fit to face Scotland on Friday, according to Wales coach John Hartson.
A heel problem has prevented him training fully with Chris Coleman's squad ahead of the Group A game.
But Bale and Celtic defender Adam Matthews, who has an ankle injury, are expected to line up at the Cardiff City Stadium.
"Gareth Bale came down to the training ground today and worked with the physio," said Hartson.
"We feel he will be okay for Friday. It was just a case of getting him ready.
"Adam Matthews did the same as Gareth, but we feel they will both be fine."
Joe Ledley, who was the third Wales player to miss Tuesday's training session, rejoined the group on Wednesday and will be available.
