The 23 year-old Cardiff Blues openside was forced out of Saturday’s Grand Slam game against France at half time, after damaging his right shoulder late in the first half of Wales’ 16-9 victory. He underwent an MRI scan on Sunday and has since undergone further examinations in Cardiff. However, this morning Warburton revealed to Telegraph Sport that he has been referred to a specialist in London in a bid to establish the full extent of the problem. “I have had the initial scans and examinations, but I’m going to see a specialist in London to hopefully get it sorted,” said Warburton. “When that will be, I don’t know as yet. I hope it’s soon because not knowing isn’t good for my head.” Warburton has been bereft of good fortune throughout the Six Nations, suffering a dead leg in the first half in Dublin and a knee injury in the opening 40 minutes against England at Twickenham. He was subsequently replaced at half time in both games and subsequently missed the home games against Scotland and Italy. He was then withdrawn at half time on Saturday after a first half collision that left him unable to lift his arm. There has been some improvement since the weekend,” added Warburton. “However, it’s hard to tell how much. It’s still painful.” The outcome of the examination will determine whether Warburton will play any part in the Blues’ bid to reach the semi-finals of the Heineken Cup and to catapult their way into contention for a play-off spot in the RaboDirect Pro 12. In terms of Wales, the national team will fly out to Australia in June for a three Test series against the Wallabies. Coach Warren Gatland will be keen to have his back row talisman on board for a series that Wales will be confident of winning on the back of their Grand Slam winning Championship campaign.
