Mackenzie Martin
Welcome back, Cardiff!
That maul drive went about 20 metres, before Cardiff worked it wide and Mason Grady hit a gap.
Cam Winnett got it back inside, before Harri Millard is able to pop inside to substitute to Martin.
A huge kick from Tinus de Beer and they're only seven points behind!
Cardiff 19-33 Glasgow Warriors
Glasgow get back down into Cardiff's 22m, courtesy of another crashing run for Sione Tuipulotu. This time though, it's turned over by Ben Donnell.
The problem for Cardiff is Evan Lloyd has been injured and now Liam Belcher has had to be replaced.
I think that means uncontested scrums...
Cardiff 19-33 Glasgow Warriors
Glasgow make three changes in response. Jamie Bhattie and Patrick Schickerling are on, the latter making his debut, in the front row. Richie Gray is on behind them.
Rory Sutherland, Sam Talakai and Alex Samuel are off.
Ed Byrne
Cardiff are still going, and eventually they crash over through half-time substitute Ed Byrne.
He gets really low and Glasgow just cannot hold him up out wide. Superb kick from Tinus de Beer as well.
Cardiff 12-33 Glasgow Warriors
Caridff win a free-kick and punch it straight up the guts. They're pounding on the Glasgow door... but they're held up.
However, we're coming back for a Glasgow offside. Another chance for Glasgow.
Cardiff 12-33 Glasgow Warriors
It's a messy start to the second-half from Glasgow as Tinus de Beer causes immediate chaos. The crowd are loving the impact from the South African.
Glasgow are camped back on their own try-line and Matt Fagerson coughs up the ball. Scrum to Cardiff on the 5m line.

Wholesale changes at the break by Cardiff head coach Matt Sherratt after that defensive horror show in the first half.
He has changed the entire front-row with Evan Lloyd, Ed Byrne and Rhys Litterick all on.
New Wales scrum-half Ellis Bevan and fly-half Tinus de Beer also take over the reigns.
But better news is that centre Ray Lee-Lo has recovered from his knock.
HT: Cardiff 12-33 Glasgow Warriors
While Glasgow have been excellent in attack, Cardiff have been extremely poor defensively.
Gethin Jenkins is the Cardiff defence coach. He'll be absolutely fuming at the number of missed tackles.
In attack, they're getting in the right areas but they've coughed up a few chances.
Can Cardiff find a way back into it second-half? Getting hitting those thumbs.

Ryan Wilson
Former Glasgow Warriors player on Premier Sports
I don't know which coach will be more disappointed.
Cardiff have played a lot of rugby, Sheedy's boot has put them in behind. They've made mistakes and Glasgow have pounced on them.
Franco Smith will be thinking Glasgow haven't fired many shots, not played much rugby - and then the tries came from nothing.
An absolute whirlwind of a first-half, with 45 points scored in 42 minutes of rugby.
Cardiff have looked decent going forward, but Glasgow have sliced them open surgically whenever they've had the ball.
The Warriors are already heading back to Scotland with a try-scoring bonus point.
I need a lie down.

The Arms Park has been stunned into silence. The home crowd can't believe what they've just seen over the past nine minutes.
Devastating by Glasgow and a real lesson for Cardiff, who bizarrely have probably had more of the ball this half.
Huw Jones
Glasgow have their fifth and it's another thing of beauty.
Tom Jordan collects a high ball on the halfway line, swivels by two tackles and delays his offload.
He waits and waits... and pops to Jones steaming in on the inside.
They have been unbelievably clinical.
Cardiff 12-26 Glasgow Warriors
There was a change from Cardiff a few minutes ago. Rey Lee-Lo looked like he was struggling with an injury trying to stop Kyle Rowe scoring.
The veteran Samoan is off so Mason Grady switches to midfield and Gabriel Hamer-Webb is on the wing.
Sione Tuipulotu
Tuipulotu is going, he's going, he's gone!
The Scotland star runs at Sheedy's shoulder, pummels through it, then dances and skips through another two tackles to roll over the line.
He's one of the best in the world when he gets going like that.
Tom Jordan knocks over the kick and Glasgow put a bit of daylight between the sides.
Tom Jordan
More pressure from Cardiff but this time Glasgow's defence is holding strong...
And it's been stolen! Tom Jordan snaffles the ball in midfield and pins his ears back, pumps the legs and sprints 60 metres to the try line.
A score gift-wrapped by Cardiff, and particularly Callum Sheedy who threw the intercept.

Wales head coach Warren Gatland is in the Cardiff Arms Park crowd this evening and will be pleased by what he's seen from his two props Corey Domachowski and Kieron Assiratti who are doing a number on Glasgow at the scrums.
Kyle Rowe
Glasgow hit straight back!
From a scrum in Cardiff's 22m, the ball is straight into the hands of Sione Tuipulotu. He runs full pelt into Callum Sheedy, who is sat on his backside before he can register the hit.
The ball is recycled and Rowe breaks a weak double tackle to trot over. Cardiff will be fuming.
Tom Jordan misses the kick and the score is level.
Cam Winnett
Cardiff's scrum obliterates Glasgow and the ball comes out to Mason Grady who pumps it further forward.
Callum Sheedy orchestrates his back line, finds Ben Thomas, who bullets the ball flat to Winnett and he's able to bounce one tackle and spin over.
Cardiff can go from first to fifth gear in the blink of an eye.
Sheedy drags his kick wide.

The home crowd are loving that counter-ruck by Cardiff, led by Josh McNally.
Given how good the Glasgow driving lineout usually is, that feels like a big win for Cardiff to hold out from five metres out.
Arms Park is coming to life.
