Johnny Matthews grabbed a try just before the interval

Warriors leave Belfast with two bonus points but they'll be disappointed it isn't more after being camped in the Ulster 22 for the last ten minutes.

It was a mixed bag from the Scotstoun men with errors proving costly on the scoreboard, but there was enough in the performance to show there's more to come from this Glasgow squad.

Glasgow tries came from George Horne, Johnny Matthews, Jamie Dobie and a penalty try after Rufus McLean was illegally tackled in the corner. Duncan Weir and Ross Thompson shared the other points from kicks.

Ulster also scored a penalty try as well as touchdowns from Brad Roberts, Marty Moore, Nick Timoney and Nathan Doak.

Warriors went into the break ahead but will rue a third quarter that saw Ulster go ahead.

"The big one was the 20 minutes after half time," said Glasgow Head Coach Danny Wilson. "We talk about that period being a very important match-winning quarter and we lost that period three tries to one.

"Two tries went against us, one that bounced nicely for them and one that was charged down so that was a little bit disappointing.

"Generally we exited poorly but I was proud of our physicality and the effort to get back into the game and we scored some brilliant tries.

"To come away from the Kingspan with two points is a positive and another was we looked fitter than Ulster in that last 20 minutes."

Glasgow now prepare to host The Sharks at Scotstoun next week.
