Williams gives Wales an injury scare

Wales coach Warren Gatland is anxiously awaiting test results on openside flanker Martyn Williams, who limped off from Cardiff Blues' 16-15 win over Ulster just after half-time.

Wales coach Warren Gatland is anxiously awaiting test results on openside flanker Martyn Williams, who limped off from Cardiff Blues' 16-15 win over Ulster just after half-time.

Williams, who was persuaded out of international retirement by Gatland last year to play a pivotal role in Wales' Grand Slam, will have an ankle x-ray on Monday.

He is set to play a key role for one more season for Wales, and will probably make his international exit after the B&I Lions tour next year, and Gatland, who has bemoaned the lack of a top-notch openside in Wales recently, will be crossing most digits that the injury is not serious.

The Blues also lost try scorer Leigh Halfpenny who was carried off after taking a knock.
