Wales head coach Warren Gatland has revealed that Liam Williams is likely to start his side's World Cup opener against Uruguay.

A foot problem has kept the 24-year-old out of action since June, and despite suffering pain in recent training sessions, he is likely to be handed the responsibility of filling the void left by Leigh Halfpenny's absence due to a knee injury.

"We want him to start against Uruguay because he's going to need some rugby," Gatland told reporters. "He's been running with us. He's had a bit of pain but it's nothing to do with the injury.

"We fitness-tested him at the end of last week and his results were as good as some of the top players in the squad.

"He's naturally going to be fit given his body frame, but he might not play for 80 minutes because we have to think about the England game the following week."
