Webber, who joined the club in pre-season, will link up with Charlie Beech and Anthony Perenise in the front-row. Stuart Hooper captains the side, with Dave Attwood joining him in the second-row.
There is also an exciting debutant in the back-row, with Mat Gilbert coming onto the openside flank for his first appearance for the club. Ben Skirving also returns at number eight, with Nick Koster shifting to the blindside.
Fly-half Tom Heathcote returns from training with Scotland to partner Mark McMillan in the half-backs, with young flyers Olly Woodburn and Richard Lane on the wings. The bulldozing duo of Ben Williams and Matt Banahan combine in the centres, with Bucharest hat-trick hero Jack Cuthbert starting at fullback once more.
On the bench, Ireland's most capped scrum-half Peter Stringer is in line to make his debut in a Bath jersey, with both Ross Batty and Semesa Rokoduguni returning to the squad.
Meanwhile, the Chiefs have looked to utilise their squad to the full for this weekend's fixture. And that means a complete new-look starting XV from that which faced Leinster a week ago.
Skippering the side and set to make his first-ever competitive start for the Chiefs is summer signing Kai Horstmann, who has now fully recovered from a hamstring injury. Whilst also set to make his debut for the club is Fijian flyer Watisoni Votu, who after a protracted visa process, is finally ready to unleash his attacking talents.
England Under-20s starlets Jack Nowell, Sam Hill, Henry Slade and Luke Cowan-Dickie all start, whilst there is plenty of experience around the park in the shape of Nic Sestaret, Craig Mitchell, Damian Welch and Ben White.
