CENTRE Jack Dixon, fly-half Angus O’Brien and scrum-half Charlie Davies will start for Newport Gwent Dragons against the Scarlets tomorrow (kick-off 5pm).

Dixon, who came off the bench for Adam Warren in Montpellier, replaces ankle injury victim Tyler Morgan in the midfield.

Wales international Morgan suffered the injury in training this week and misses out on Judgement Day IV at the Principality Stadium.

The double change at half-back sees O’Brien come in for Dorian Jones and Davies get the nod over South African Sarel Pretorius.

Jones and Pretorius both drop to the bench where they are joined by fellow back Geraint Rhys Jones and forwards Rhys Buckley, Luke Garrett, Lloyd Fairbrother, Matthew Screech and Ed Jackson.

Second row Rynard Landman will make his 50th start for the region, as the Dragons bid to claim their first win at the home of Welsh rugby.

Meanwhile, Scarlets vice-captain Scott Williams has been named in the West Wales region’s starting line-up for the first time since the final day of last season.

The 25-year-old Wales centre returns to action following a knee injury last September.

Head coach Wayne Pivac makes another five changes to the backline that took on defending champions Glasgow Warriors at Parc y Scarlets a fortnight ago.

Liam Williams, Steff Evans and Hadleigh Parkes make up the positional changes, moving to right wing, left wing and outside-centre respectively, while Aled Davies replaces Gareth Davies at scrum-half and Michael Collins comes in at full-back.

Lewis Rawlins is the only change to the pack as he makes his first appearance since the Scarlets’ defeat to Connacht in late January.

Former Wales Under-20s hooker Ryan Elias joins props Dylan Evans and Peter Edwards on the replacements bench alongside Jack Condy, who is hoping to appear for the first time since suffering a shoulder injury at the start of the year.
