Rugby: Wales outhalf Rhys Priestland is facing a race against time to be fit to face France in the Rugby World Cup semi-finals. The Scarlets player has been struggling with a shoulder injured suffered in the final few minutes of the last-eight win over Ireland.

Priestland was forced to wear a sling on his left arm on Sunday and Monday and has been undergoing intensive rehabilitation in a bid to be fit.

Head coach Warren Gatland is willing to give Priestland, who has enjoyed a meteoric rise on the international stage, as long as possible to prove his fitness - although Stephen Jones, the most capped Wales player, and James Hook could slot in.

Priestland remains the only doubt for the clash with Les Bleus, with Luke Charteris (shoulder), Sam Warburton (groin) and Jamie Roberts (nose) all expected to play on Saturday at Eden Park.

Gatland will confirmed his side on Thursday - and Hook admits he is ready to step in to the No.10 shirt if needed.

"I would be there if needed and selected," said Hook, who starred at full-back for their opening two World Cup games until a shoulder problem sidelined him. It was really difficult (watching on Saturday), but you get caught in the emotion on the bench and get behind the boys.

"It was a terrific performance and it was nice to get on and have a couple of minutes to savour a little bit at the end. Rhys has taken his chance superbly, and he fully deserves the credit he has been having. The young players spur you on with the energy they bring in training and off the field. The older boys are feeding off that, which is good and healthy for the team."

Hook, meanwhile, is well aware of the challenge France will pose at Eden Park.

"France were great against England on Saturday," he added. "They were clinical, took their chances well, kicked their goals and looked strong from the start. Everyone knows about French flair and their unpredictability."
