Not the best performance from Ulster but in the end the game swung on the red card for Paul Willemse.

The games, and air miles, keep racking up for interim head coach Richie Murphy in his Ulster tenure with the side now to face Clermont at the Stade Marcel Michelin in the Challenge Cup quarter-finals next weekend.

Never an easy place to go but Ulster did win there on their last visit.

You can read Jonathan Bradley's match report from the last-16 win here and that's all from us.

Thanks for joining!

Man-of-the match David McCann speaks to ViaPlay Sports after the final Whistle:

"I mean it was very tough at the start.

"It was very physical in the first half and i think our discipline let us down.

At half-time we knew we had to be better and focused on getting faster line speed.

"We came out and changed our attitude in the second half and capitalised on the Montpellier red card.

"its brilliant to be in the quarter-final of the Challenge Cup. We probably played better against the Stormers last week but got nothing.

"But we have lots of momentum now going forward into next week."

It's all over in the south of France and Ulster have the victory.

Six tries send the Irish Province into a Quarter-final meeting with Clermont Auvergne, back in France, next week.

Will Addison, Rob Baloucoune, Scott Wilson, David McCann, Stuart McCloskey and a Penalty Try grabbed Ulster the victory.

Paul Willemse scored and was also sent off for the hosts with Aubin Eymeri also grabbing a first-half score.

It was far from perfect and Ulster were greatly helped by a period playing against 12 men, but the result is all that matters.

The home side back to 14 men, but are now defending a five-metre lineout.

Montpellier threaten with a break but it's intercepted by John Cooney and the ball goes left where Stewart Moore kicks to touch for a 50/22, therefore, Ulster retain possession. Smarts.

Surely the Ulster men will take the game now.

There is just so much space out there.

make that 12 men!

Vano Karkadze comes in from the side and walks from the pitch. The referee had warned them previously.

The Montpellier lock is sent from the field for 10 minutes after intentionally standing on Robert Baloucoune's arm as the winger lay on the ground. 13 v 15 now.

Ulster still pushing hard as they surely must grab a score. Another penalty five metres out, it's tapped this time.

And again the Irish Province come up short.

Steven Kitshoff looks like he's going to bundle over but he is just short. Then the balls breaks back loose and Nathan Doak is turned over on the deck.

Ulster win another penalty for an offside infringement.

They kick into the corner.

It's another missed chance for the visitors.

Multiple phases lead to John Cooney popping off a short ball to the in-rushing Dave Ewers five-metres out. But the big replacement can't take the ball and it bounces into the arms of a relieved Montpellier defender.

Ulster must make one of these count.

Ulster thrust forward in the scrum.

Nick Timoney appears to lift the ball at the base a tad early as it looked like he just had to keep it at his feet and march over the line.

His dive for gory is stopped as he fails to ground the ball, back for an advantage though.

All new front row for Montpellier for this scrum that is now resetting for the third time...

It's a crooked throw from Montpellier on their own five-metre line and now Ulster have a scrum. This is a big chance.

Not surprisingly Ulster are now starting to turn the screw at scrum-time.
