"He's been an outstanding player for us and did incredibly well to come back from his injury in the summer to get back up and running and get fit.
"He's been playing outstandingly well, and did pretty well again yesterday until his injury.
"He's a huge loss, but we've had quite a few of them and we've just got to get on with it."
Wales, who face South Africa in the quarter-finals at Twickenham on Saturday, have yet to call-up a replacement for Williams.

Having overcome foot surgery in June to play in the tournament, Williams was concussed in the 28-25 win that helped knock out hosts England at the pool stage.
He returned against the Wallabies after missing the victory over Fiji.
Williams' injury comes after Wales lost wing Hallam Amos to a dislocated shoulder against England.
Ospreys wing Eli Walker was a late withdrawal ahead of the tournament because of a hamstring injury.
Roberts is the first inside centre to give Gatland a medical scare, but did not have any concussion assessment after coming off.
In June, Roberts' regular midfield partner Jonathan Davies (knee) was ruled out of the World Cup, with Scott Williams (knee) and Cory Allen (hamstring) later joining him in being sidelined.
Full-back Leigh Halfpenny and scrum-half Rhys Webb were ruled out on the eve of the tournament after being injured during the final warm-up game against Italy in Cardiff.
