Warriors head coach Sean Lineen always planned to freshen things up but injuries have also played their part.

“We’ve made a few changes, but it was always in the plan,” said Lineen, whose side face a quick turnaround from Sunday’s win over the Scarlets which maintained their 100% start to the season.

“However, we’ve had to make a couple more through injury. This week will really test the depth of our squad.”

Two of the six changes are in the backs where Scotland Sevens international Colin Shaw takes over on the left wing from Thom Evans, who is ruled out with a trapped nerve in his neck.

Mark McMillan comes in for Chris Cusiter at scrum-half to partner Dan Parks, with Cusiter unavailable for family reasons.

Captain Alastair Kellock starts on the bench, with Dan Turner promoted to the second row, while flanker Calum Forrester is given the nod ahead of Kelly Brown.

Neither prop is retained, as Jon Welsh is rested after three big performances against Wasps, Munster and Scarlets, while Moray Low is nursing a recurring ankle problem.

Samoa international Justin Va’a will make his first appearance of the season, with Ed Kalman brought in at tighthead.

Glasgow also face the Dragons in the Heineken Cup this season and Lineen added: “This is the first of four games against the Dragons this season, but it’s all about Glasgow.

“We’re going down there with real intent. There’s a confidence and a belief in this squad and we’re hungry to get a result.”
