The elder sibling has been included in the Warriors’ second-row for the Scotstoun match, and changes limited by the home side for the first European encounter in the west-end ground for almost two years.
Jamie Bhatti’s promotion to start is the only alteration from the side that took to the field at the Stade Marcel Deflandre, with the Warriors earning a losing bonus-point at the home of last season’s runners-up La Rochelle.
Now, with the champions arriving north WIlson is preparing to “produce another physical display and take our opportunities to get a home win against another good Exeter team.
“Leaving La Rochelle with a losing bonus-point gives us a big opportunity this weekend.”
George Turner and Zander Fagerson join Bhatti in an all-Scotland front-row, with Bhatti and Turner having also started Glasgow’s victory over the Chiefs at Scotstoun back in 2018.
Jack Dempsey continues at number eight in a back-row completed by Rory Darge and Matt Fagerson.
Ali Price at scrum-half will be captain with Ross Thompson making his first home European start in an otherwise unchanged side.
Exeter have, of course named Richie’s younger brother Jonny Gray in their second row, with Scotland’s record-breaking captain Stuart Hogg also included.
Warriors have also requested visiting fans refrain from attending with faux Native American headdresses and do not participate in the chant of the 'Tomahawk Chop' during the match.
