Glasgow Warriors tackle RaboDirect PRO12 leaders Leinster on Saturday with a side showing four changes.
Fourth-placed Glasgow drew with Connacht in their last outing, but are denied the services of Graeme Morrison as the centre is set to start Scotland's RBS 6 Nations clash with France on Sunday.
Alex Dunbar takes Morrison's place with Troy Nathan moving to inside centre, while Colin Shaw comes on to the wing in place of Tommy Seymour, who has been named among the replacements for the Firhill clash.
Tighthead prop Mike Cusack is set to make his first appearance since New Year's Day after recovering from an ankle injury, while Nick Campbell is poised to start at lock in the two further changes.
Blindside flanker Rob Harley will captain the side, who are seeking a first double over Leinster and an eighth victory in nine home encounters in all competitions.
European champions Leinster, who twice beat the Warriors in Heineken Cup competition this season, have won 17 and drawn one of their last 18 games since losing to Glasgow in Dublin last September.
Glasgow head coach Sean Lineen told the Warriors website: "Three of our next four games are at home, and it's vital we exploit that to our advantage, starting with Saturday's match against Leinster.
"They've got a big squad with top players right throughout it. Their rugby is the definition of relentless and they punish every mistake.
"The players have risen to the challenge so many times already, and tomorrow is another day for standing up and being counted so that we continue to stake a strong claim for a place in the top four."
