Glasgow head coach Sean Lineen will hand debuts to three players when they begin their RaboDirect PRO12 campaign against Ulster at Ravenhill on Friday.
Inside centre Troy Nathan, tight-head prop Mike Cusack and winger Tommy Seymour will all make their bows for the Warriors. A further two players, lock Nick Campbell and back-rower Rory Pitman, are in line to make their first competitive appearances for the club from the bench.
Lineen said: "I've been very impressed by how our new signings have made themselves at home and also made themselves heard."
He added: "I'm really looking forward to them delivering in a game context and they'll be helped to do that by a core of guys like Rob Dewey, Colin Shaw, Colin Gregor and James Eddie who know what being a Glasgow player is all about.
"Rob Harley will captain the team again. I was very happy with how he took to the role last week. He's a guy who will lead from the front and take others with him.
"We've had a very positive summer in terms of the players' desire to go out and do well for the Warriors - it's now about translating that into a good start to the RaboDirect PRO12 season on the field.
"We've got a lot of guys unavailable because of the IRB Rugby World Cup, and while that presents a number of challenges, it also gives other players the chance to really step up and make their mark."
Seymour told www.glasgowwarriors.org: "It's fantastic to be making my Glasgow debut in a place that means a lot to me from my Ulster days.
"There's been a good vibe around the squad in pre-season and the players are desperate for the competitive action to begin.
"Ravenhill can be a difficult place to go as an opposition player, but we've shown the attitude and the ability to win there in the past, and we certainly travel with confidence."
