Glasgow really on top for the last 5 minutes, going over again through Ryan Grant, only for great work from Kearney to hold him up.

@Joe McTaggart Hard to tell what happened to O'Driscoll although he looked to be limping with an ankle injury.

Nooooooo

Great response from Glasgow, forcing a turnover straight from the kickoff. Matawalu takes a quick penalty, and after some big carries from the forwards he pops up under the posts to snipe over the line. Hogg adds the extras to give his side an early lead.

What happened? I'm assuming collision? Shoulder?

What happened bod

Worrying pictures for Leinster and the Lions as O'Driscoll limps off early.

Good spell for Leinster as they recycle the ball well. Big carries from Heaslip and Strauss in particular bring Leinster to the Glasgow 22, where again Glasgow are guilty of not rolling away. Sexton makes no mistakes this time to open the scoring.

Leinster win a free kick at the first scrum of the day and Heaslip takes a quick tap, making good yards. At the subsequent break down Ryan Wilson of Glasgow is penalised for not rolling away. Sexton however pulls his kick badly wide.

Glasgow go very close to snatching an early score, Horne showing great hands to put Van der Merwe in past the defence. Leinster scramble and recover until eventually great work from O'Driscoll forces a turnover. 5 minutes gone.
