The Carmarthen Quins man has answered an SOS call from Director of Rugby Lyn Jones to solve their midfield
crisis.
Ashley Smith was the only fit centre before Williams’ arrival after Tyler Morgan, Jack Dixon, Pat Leach and Ross Wardle were all sidelined by injury.
Jason Tovey will start at full-back for Newport Gwent Dragons in tomorrow’s Guinness Pro12 clash with Ulster in Belfast.
The 25-year-old fly-half makes his return to the squad after a passport mishap meant he could not travel to Paris to face Stade Francais a fortnight ago.
Captain Lee Byrne is out with a hip injury while Hallam Amos and Tom Prydie are on Wales duty, so Tovey is given the number 15 jersey.
Angus O’Brien will get the chance to continue his impressive start in regional rugby as he makes his third appearance in a row at fly-half.
Ulster are without captain Rory Best, Jared Payne, Tommy Bowe and Craig Gilroy and Chris Henry because of Ireland duty, although Stuart Olding is released to start at full-back and Robbie Diack is among the replacements.
Influential overseas players Ruan Pienaar and Nick Williams are also absent from the Irish province’s squad.
Head Coach Kingsley Jones has told his players to have no fear on their Ravenhill trip.
He said: “We are going to be without lots of players for Ulster but the positive thing is that lots of young boys will get opportunities.
“They have to go to Ulster without fear and give it a go. It doesn’t come any more intimidating that Ravenhill but I’ve always had the philosophy, whether as a player or coach, that away from home you have everything to gain and nothing to lose.
