Nick Grigg opened the scoring for Warriors

Warriors started brightly and led 19-17 at the break with tries by Nick Grigg, Ratu Tagive and Matt Smith with Brandon Thomson adding a couple of conversions.

The second-half saw Ulster dominate possession, territory and the scoreboard with 33 unanswered points, but Glasgow head coach Dave Rennie believes that there are still positives to take from proceedings despite the result.

"I thought we played pretty well in the first half," he said.

"We led 19-7 with about 10 minutes to play in the half, so we were in a good place.

"I thought Ulster were sharp, but we'll be better for it next weekend."

In total, 12 players were making their first appearances in a Glasgow jersey, including 18-year-old scrum-half Jamie Dobie and academy prospect Marshall Sykes. Whilst in no way an ideal start to their Glasgow careers, the Warriors boss is confident in his squad's development.

"We got a bit of a lesson in the second half, but we had a lot of young men on the field that deserved their opportunity," said Rennie.

"They've worked hard in pre-season and will learn a lot from today."

The two sides meet again in just a week's time, as Scotstoun plays host to The Famous Grouse Pre-Season Challenge on Saturday 14 September (ko 2.30pm). Rennie expects to have a few more players available for selection, and is targeting an improved performance in front of the Warrior Nation.

"I thought we were good early on today - we just didn't look after the ball well enough in the second half," he said.

"Ulster were clinical and asked a lot of questions of us. We're not too disheartened though, we'll bounce back next week.

"There'll be a handful of guys that will come in next week - some guys will come back from injuries and international camps and so on. Like I said though, we'll be better for it when we run out at Scotstoun next week."
