gregor townsend has ordered an action replay of Glasgow Warriors blistering start to their Guinness PR012 campaign when they take on Cardiff Blues tomorrow.

The Scotstoun coach was delighted with his side's 22-20 win over defending champions Leinster last weekend.

But he reckons that win will count for nothing if they can't keep the momentum going when they travel to face a Cardiff side who also won their opening game.

He said: "Cardiff had a good away win last week against Zebre and will be looking to build on that tomorrow

"We're expecting a tough challenge at the BT Sport Arms Park.

"Our players showed great character and effort to dig out a victory against the defending champions last week and we'll be looking for a similar spirit away from home this weekend.

"Our performance in the final quarter has given us plenty to work on this week at training and an extra 24 hours' recovery has really helped our preparations."

Glasgow will be boosted by the return of Sean Lamont for the match, which is live on live on BBC ALBA, kick-off 4pm. The 33-year-old came off the bench in last week's win and will replace Lee Jones on the left wing.

In the pack, Alex Allan has been given the nod at loose-head for the second consecutive game, with Pat MacArthur replacing Fraser Brown at hooker and Rossouw de Klerk coming in for Euan Murray at tight-head to complete the front-row.

Tim Swinson replaces Leone Nakarawa in the second-row and he'll partner Jonny Gray in the engine room.
