Scotland Under-20 centre Mark Bennett has been rewarded for his try against Munster with a starting place when RaboDirect PRO12 leaders Glasgow face Scarlets on Friday night.
The 20-year-old scored his second try in three appearances this season in the 51-24 win and replaces Sean Lamont, who drops to the bench.
Other changes see Henry Pyrgos replace Niko Matawalu at scrum-half, with Tom Ryder coming into the second row and props Moray Low and Gordon Reid also recalled.
Head coach Gregor Townsend said: "Mark played really well for Scotland Under-20s and has also impressed for Stirling County.
"He has been one of the stand-out players in training this week and did well when he came on against Munster, so he's earned the opportunity to start in such an important game."
The Warriors have won eight of their last nine encounters with the Welsh regions but have not won at Parc y Scarlets since May 2010.
Townsend added: "Everyone has come back fresh from a week off, so we're looking for that to benefit us during the run-in. The skill level and commitment of the players has been excellent all season and we'll need another big performance tomorrow night."
