A small spark from Glasgow as Matawalu breaks down the wing. They recycle the ball and gain some yards on a back peddling Scarlets defence. Swinson crosses in the corner but the ref just wants to check the TMO.

Another cheer as Cusiter is bundled into some of the hoardings. That's just about the most exciting thing to happen in this game.

A cheer rings around the ground as the ref clocks the ball on the back of the head!

Glasgow are looking to dominate up front with a rolling maul making 10 metres. But they aren't clinical enough as their maul is wrapped up just short of the line. Scrum 5 Scarlets.

Glasgow chip and a good chase piles the pressure on the Scarlets' cover. Williams does well to mop up but they can only clear it 15m. Glasgow with the net gain there.

Robert Harley living on the edge at the breakdown. The ref pings him for hands in the ruck under his posts.

Looking at the replay, it was a poor decision by the assistant ref. Nothing at all in that one.

The ref is consulting his touch judges about foul play in the line out. Penalty Scarlets.

The Welshmen make up for their earlier poor form, winning a penalty in their own 22 at scrum time.

Williams is back up now looking a bit groggy but he should be fine to continue.
