Few of Scotland's summer tourists are involved. Jonny Gray missed the tour but starts on Saturday as does Rory Hughes, in the No 15 jersey, and Oli Kebble, the South African prop, gets a run at loosehead. Australian international scrum-half Nick Frisby makes his debut with half-back partner Brandon Thomson, although much of the focus will inevitably fall upon substitute Adam Hastings who is widely tipped to inherit Finn Russell's No 10 shirt following the latter's move to France.
DTH van der Merwe should be fit for the start of the PRO14 on 1 September, although Brian Alainu'uese's ankle may take a few weeks longer. Warriors will have to cope without experienced forward Tim Swinson who is out until December with a broken leg.
USA Eagle David "Tevita" Tameilau has been brought in to add some ballast to Glasgow's breakaway unit, but fans will to wait a bit longer to see him in action.
Speaking ahead of Saturday's game in Perth, Dave Rennie told The Scotsman: "We've got good depth in a number of areas. We felt that we needed a bit more of a physical presence in the loose forwards, and hopefully we'll get a bit more game time out of Adam Ashe this year; he started last season pretty well and then was pretty much injured from round eight. And we've brought in Tevita but we're not going to rush him, he's only just arrived so he's not going to play in the early stages until we get him in the sort of condition we need him in to be effective. We're pretty happy with our depth in most of those positions. There is a lot of competition for places and the attitude has been great."
The Warriors coach highlighted a number of areas his side must improve upon if they are to better last season's semi-final exit in the PRO14; basic handling, clear out, error count and he name checked champions Leinster's patience while going through the phases. "I just think we made far too many errors, we turned over too much ball,"said Rennie. "Some of that is skill-set under pressure and some of that is patience to build. So, that's an area we have put a lot of time into, our catch-pass to be better under pressure. We still want to play and challenge teams, but if you look at Leinster, it was their ability to hang on to the ball for long periods and build pressure, to force errors or win penalties. "They are pretty impressive, so that's an area we've got to be better."
