That is it for our live coverage of this instant classic URC clash. Thank you for following the game with us. Goodnight.

This win is sweet revenge for the Bulls, who slumped to a shock defeat at home to the Warriors in the URC final last season.

FULL-TIME: GLASGOW WARRIORS 19-26 BULLS. The visitors come away with an incredible result, the first South African team to win at Scotsdown Stadium. They had a chance to deny the Warriors a losing bonus-point, but Willie le Roux turned down the shot at goal and kicked into touch to bring an end to a thrilling showdown.

CONVERSION, WARRIORS, HORNE. 19-26.

TRY, WARRIORS, SMITH. 17-26. There's life in the Warriors yet. They run circles around the Bulls' tired defenders to score a crucial try.

The conversion is off target.

TRY, WARRIORS, STEYN. 12-26. The dam wall breaks and the home side finally cross for their second try of the game.

The Bulls survive another Glasgow Warriors attack and come away with a scrum just outside their own 22.

This Bulls defence should be commended for how they have swamped the Warriors.

Oh this game has opened up now. If not for unforced handling errors, they would have been more tries in this half.

This is impressive work by the Bulls, who turn defence into attack in the blink of an eye.

Mayhem as the Glasgow Warriors, through Rory Darge, breaks away from their own 5m line. The Bulls rush back in numbers to stop the attack and pinch a turnover.

Akker van der Merwe fields a well-weighted grubber kick to pin the Warriors back in their own half.

The Warriors are trying to run from deep, but the Bulls' rush defence is working well.

From the lineout, the Bulls lose the ball forward and it is then played from an offside position. Penalty to the Glasgow Warriors. That comes as a big relief to the hosts.

Dominant. That is the only way to describe the Bulls' scrum at the moment. They just won another penalty at the set-piece. Goosen kicks to the line.

A slight knock-on inside the 22 gives the Bulls another attacking scrum.

There's just over 15 minutes left in this game. The Glasgow Warriors have to score next to stay in the contest here.

And as if the scoreboard isn't bad enough for the Warriors, Bulls have just pulled off Devon Williams and introduced two-time World Cup winner Willie le Roux.

The Bulls' tactical switch-up and game-management so far in this second half have put them firmly in control of the contest.

CONVERSION, BULLS, GOOSEN. 7-26.

TRY, BULLS, KRIEL. 7-24. And now the Bulls are pulling away. Kriel just scored another five-pointer after De Klerk pounced on a Glasgow Warriors error at the back.

Suddenly the Bulls have a 12-point lead in Glasgow. This is a superb turnaround by the visitors.

PENALTY, BULLS, GOOSEN. 7-19.

The Glasgow Warriors look shell-shocked by this second half surge from the Bulls.

CONVERSION, BULLS, GOOSEN. 7-16.

TRY, BULLS, VAN DER MERWE. 7-14. The Bulls crash over from an unstoppable driving maul.

The pendulum has swung in the Bulls' favour. Glasgow are being out-muscled and out-played here.

Wilco Louw is making up for his yellow card with a scrummaging masterclass at the start of this second half.

The Bulls have Glasgow on the back-foot here.

This is a different Bulls team that came out in the second half. They look more energised than before the break.

KICK-OFF: We're back with the second half.

HALF-TIME: Glasgow Warriors 7-9 Bulls.

PENALTY, BULLS, GOOSEN. 7-9. The flyhalf knocks over a third penalty to put the Bulls in front again.

Goosen will line up a long range effort for the Bulls.

The Bulls have yet to show any kind of attacking enterprise in this half. But with the knowledge of a penalty advantage, they swing the ball wide from a scrum. But the referee brings them back for the penalty.

CONVERSION, WARRIORS, HORNE. 7-6. The scrumhalf strikes his team into the lead.

TRY, WARRIORS, DOBIE. 5-6. A floated pass leads to the Bulls undoing. That is a deserved touchdown for the Warriors, who have been bashing away at the door.

The Bulls concede a third consecutive penalty for not rolling away at the breakdown, and the referee gives them an official team warning.

Or not. Steyn reads play beautifully and intercepts a Bulls pass. He tries to skin Papier on the outside, but the scrumhalf does well to halt him in his tracks. The hosts keep the ball alive and work their way deep into Bulls territory.

The referee awards a free-kick to the Bulls at a Glasgow lineout. The Bulls can have a crack at the tryline now.

Wessels is like a one-man wrecking ball.

Wessels just knocked a Glasgow ball-carrier back in the tackle with a huge hit.

But this attacking endeavour by Glasgow is relentless.

Another scoring opportunity is passed up by the Warriors, as they cough up possession, allowing the Bulls to put in a great clearance kick.

Glasgow are playing with an advantage. But the Bulls do not concede an inch of ground to them. However, the visitors do get pinged for not rolling away on the ground.

YELLOW CARD, BULLS, LOUW. The prop will spend 10 minutes in the sin bin and despite vocal protestations from the home crowd about his sanction, the referee says while it is foul play there was a low level of danger.

The Bulls' Wilco Louw is in trouble with the officials here. He has just been caught for a high tackle.

Glasgow have bombarded the Bulls back-three will high bombs, but this time Sebastian de Klerk leaps high to win the contest and secure possession.

Papier makes no mistake with his exit kick from the restart and finds the chalk beyond the halfway line.

PENALTY, BULLS, GOOSEN. 0-6. The Bulls extend their lead with a second successful penalty kick.

But you have to find touch from that position and unfortunately for the Bulls, Goosen fails in that regard. Glasgow counter, but then Papier steals possession on the ground. Steyn goes off his feet. Penalty to the Bulls.

Here come the Warriors again. They are 10m away from the tryline. But the Bulls refuse to give up further ground and Wessels goes in over the ball to win a penalty.

From the drop-out, Jordan takes on the Bulls defence again and wins a penalty as the visitors are penalised for not rolling away.

This is good continuity by Glasgow, but then Jordan opts for a grubber kick and Williams has it covered at the back for the Bulls. Goal-line drop-out.

Moodie makes another thumping tackle in mid-field. This is an immense defensive display.

PENALTY, BULLS, GOOSEN. 0-3. Glasgow conceded a double penalty, one at the scrum and another for streaking offside.

Glasgow steal the ball off the Bulls, but back they go for the penalty.

Finally, the Bulls get the upper-hand at scrum time, earning them a penalty advantage.

Moodie is tackling like a man possessed. Phenomenal work-rate from the young winger.

The Bulls are just playing a couple of paces slower than Glasgow at the moment.

The home side go to the line again. They in full control of this game so far.

The Bulls spark to life with a counter-attack from turnover possession, but Williams' no-look pass goes straight to a Glasgow player and from there the Bulls concede a penalty.

Glasgow's contestable kicks are working wonders for the hosts. They go to the air and win the mini-battle again as Williams is dragged into touch.

It's all a bit too shaky by the Bulls. Devon Williams just had a clearance kick charged down, but fortunately for him the ball beat everyone into touch.

Nortje fails to gather the ball at the lineout and Glasgow have another attacking opportunity inside the 22.

Goosen launches a spiralling exit kick from the goal-line drop out.

In an unbelievable sequence of play, the Glasgow Warriors slice the Bulls defence open on their way to the tryline, but prop Jan-Hendrik Wessels miraculously tracks back and holds the ball up off the ground.

The Bulls' big men are disrupting Glasgow's lineout at every opportunity.

The Bulls turn down three easy points on offer and kick to the line. But they concede possession for clearing too far beyond the ruck.

The scrum is solid and the Bulls attack through their backs. Canan Moodie charges into the 22, but when he is brought down, the referee brings them back for a penalty.

After a little ping-pong between the sides, Glasgow make another handling error. The first scrum of the game goes to the Bulls.

The Bulls set-up phase-play from the kick off before Goosen clears the ball away. The Warriors opt to counter, but lose the ball in contact.

KICK-OFF! We're underway with the first half here in Glasgow… It's the Warriors against the Bulls!
