British and Irish Lions

The 20-year-old Cardiff Blues wing made his British & Irish Lions debut against the Free State Cheetahs in Bloemfontein last weekend after spending 10 days at home overcoming his thigh problems.

But he aggravated the injury at the end of the training session on Monday and has been withdrawn from the Lions replacements as a precaution.

"He was examined by the medical team this morning and was comfortable. However, in order to enable an accurate diagnosis he is currently having a scan," said a Lions spokesman.

"As a preliminary measure he will be unavailable for Wednesday's game and James Hook will take his place on the bench."

Assistant coach Graham Rowntree says The British & Irish Lions will have to be fully focussed to avoid a potential banana skin when they face The Barbarians a week today.

Three former British & Irish Lions will line-up against an England XV at Twickenham Stadium on Sunday as the Barbarians warm-up for their showdown with the 2013 tourists in Hong Kong next week.

Lions skipper Sam Warburton says the lessons he and his Welsh colleagues learnt in Australia last summer will stand them in good stead for their return visit with Britain and Ireland's elite next month.
