After progressing from the EPCR Challenge Cup quarter-finals and setting up a last-four meeting at Parc y Scarlets on April 29, the two sides clashed in the URC last weekend, with hosts Glasgow clinching a nervy 12-9 win.

In the final round of URC fixtures in the regular season, Scarlets welcome Dragons RFC to the Principality Stadium and Glasgow entertain Connacht Rugby at Scotstoun Stadium.

Scarlets have made six changes to their starting line-up, with Kemsley Mathias, Ken Owens and Javan Sebastian forming a fresh front row.

Joe Roberts and Johnny Williams return as the midfield pairing while Sam Costelow, the second-highest points-scorer in this season’s EPCR Challenge Cup, is back at fly-half.

Meanwhile, Glasgow have named a completely new pack as props Allan Dell and Lucio Sordoni line up either side of hooker Fraser Brown in the front row, Scott Cummings and Richie Gray pair in the second row, and Sione Vailanu and Rory Darge flank No.8 Jack Dempsey in the back row.

There are also two fresh faces on either wing for the Scottish region, in Jamie Dobie and Cole Forbes.

RC Toulon are another EPCR Challenge Cup semi-finalist in domestic action on Saturday – the TOP 14 heavyweights, who host Benetton Rugby on April 30, are away at Castres Olympique.

Scarlets and Glasgow Warriors have reshuffled their starting teams for their BKT United Rugby Championship (URC) games on Saturday as their EPCR Challenge Cup semi-final next weekend edges ever closer.
