Jamie Dobie's try got Glasgow back in the game

Warriors had to come from behind to earn a 17th consecutive PRO14 victory over Zebre.

Two Mattia Bellini tries late in the first half left them trailing at the break after Ross Thompson's converted try and penalty.

But Glasgow, who had Sam Johnson and Ollie Smith in the sin bin either side of the break, tightened up their defensive work, and started to turn pressure into points.

Jamie Dobie, Tom Gordon and Nick Grigg all crossed to put them four points clear of Zebre in fourth place in Conference A.

Warriors started well but the flow of the match was interrupted by a clash of heads between Michelangelo Biondelli and Gregor Brown.

The Zebre full-back had been on the charge when a quick change of direction saw him collide head-to-head with Brown.

Biondelli left the field on a stretcher after receiving treatment while Glasgow back-rower Brown - making his first start - got back to his feet but was helped off by medical staff following the impact.

Paolo Pescetto opened the scoring from the tee when play eventually resumed, although Thompson restored parity four minutes later.

Thompson then moved Glasgow in front for the first time after 23 minutes when Zebre failed to deal with Cole Forbes' grubber kick and the fly-half pounced to touch down before adding the extras.

Zebre lost Potu Leavasa to the sin bin but emerged from his absence back on level terms, with Renato Giammarioli's offload sending Bellini in under the posts and Pescetto making it 10-10.

The Warriors had Johnson yellow-carded for a tackle in the build-up to that try and Bellini scored his second in the space of two minutes as Zebre took a seven-point lead into half-time.

Glasgow were temporarily down to 13 men three minutes into the second half when Smith was penalised for a deliberate knock-on and Pescetto opened up a 10-point advantage before the full-back's punishment was up.

Smith never returned to the action but replacement Grigg was key to the move that brought Glasgow back into the game, carving a path through the Zebre defence before sending Dobie under the posts and debutant Ian Keatley kicked the Warriors within three.

Enrico Lucchin was sent to the bin as Zebre came under pressure on their own line and Glasgow's persistence paid off when Gordon emerged from the back of a ruck and stretched for the line before Grigg wrapped up the win and a bonus point, with Keatley converting both tries.

New Assistant Coach Peter Murchie was pleased to see Warriors record a first bonus-point victory of the season.

"It's always good to get five points on the road," said Murchie.

"It was a tough game that had a lot of momentum swings, but we finished really strongly in that last 20 minutes. The guys did well to see it through.

"We created a lot in attack and looked dangerous throughout the game. We knew if we could hold onto possession and make it count in the right areas, then we would cause Zebre problems."

Murchie was keen to praise the team's resilience throughout, having also had to deal with yellow card to Johnson and Smith.

"You saw there how momentum changes games," said Murchie.

"We had a tough ten-minute period just before and just after half-time, and Zebre definitely had their tails up. You clearly never want to play with 13 men, but we showed a lot of character.

"They showed a lot of guts to ride that period of the game out, and to come through it and win in the way we did was very satisfying."

The Glasgow assistant also offered an update on Gregor Brown, who was led from the field just five minutes into his first start for the club after a heavy collision with Michaelangelo Biondelli.

"Gregor looks alright," said Murchie.

"It was obviously a big collision, so we'll be careful with him over the next little while.

"Hopefully he comes through it alright and we'll see how he does in the next few days."
