Glasgow have four scrum-halves out for the RaboDirect Pro12 clash against Leinster - but will have five internationals back from Scotland duty to accompany 21-year-old number nine Sean Kennedy in the back division.
Kennedy, who is on loan from Edinburgh's Elite Development programme, will make his third appearance for Gregor Townsend's side. Henry Pyrgos and Niko Matawalu are playing for Scotland and Fiji, while Chris Cusiter and Murray McConnell are not fit. Gala's George Graham has been training with Warriors and will take his place on the bench.
Fly-half Ruaridh Jackson, who came off the bench against South Africa last weekend, lines up with fellow backs Peter Murchie, Tommy Seymour, Alex Dunbar and Tom Ryder, who were all in the Scotland squad before the start of the EMC Test series.
Glasgow also have hooker Pat McArthur, prop Moray Low and winger DTH van der Merwe back from injury.
Townsend told glasgowwarriors.org : "It's certainly unusual to have all our four scrum-halves unavailable at the same time but I've been very impressed with Sean since he joined us. His work ethic and attitude in training are excellent and, even with those other players available, he would be pushing for a starting place.
"George has come in and been very professional in his approach to training. It's a great experience for him as he has impressed a lot of people this year with his performances for Gala."
Glasgow recorded their sixth consecutive league victory when they beat Newport Gwent Dragons 37-6 at home in their previous outing.
Townsend said: "In our last game here at Scotstoun we kept up our winning run through some ambitious attacking play allied to strong defence, and that was a great way to enter the international break.
"But we know as we enter the middle third of the season that it's going to get much tougher, starting with Leinster.
"They are an exceptionally good side and will be desperate to close the gap in the table to the top four."
