Wales sweating on Biggar injury

Defending champion Isner and Kyrgios through to Miami Open third round

Wales are sweating over the fitness of fly-half Dan Biggar for Saturday's clash with Scotland after he sustained an injury against Ireland.

Biggar limped off in the 22nd minute with an ankle knock and was replaced by Rhys Priestland in the 16-16 draw in Dublin.

Priestland delivered a satisfying goal-kicking performance and helped Wales get back into the game after a 13-0 deficit against the reigning Six Nations champions.

Wales head coach Warren Gatland feels it is still too early to say if Biggar would be fit to face Scotland at the Millennium Stadium.

"Dan has a high ankle sprain, so we will know more on that in the next 24 to 48 hours," said Gatland.

"Whether he has got to be scanned or not, I don't know. It's difficult to make assessments so soon after the game.

"I thought Rhys Priestland played well when he came on, and we were happy with his performance."

Wales take on Scotland at the Millennium Stadium, Cardiff on Saturday.
