Centre James Hume’s late try capped Ulster Rugby’s 20-10 win at four-time European champions Leinster Rugby in the United Rugby Championship clash on Saturday.

The victory against fellow Heineken Champions Cup opposition will be a boost for Ulster heading into their Pool A campaign, which kicks off at ASM Clermont Auvergne on December 11.

Greg Jones went over for Ulster on 15 minutes, with Leinster responding through a Robbie Henshaw try just after half-time, but Hume dotted down in the closing stages to seal the visitors’ triumph, their first at the Ballsbridge venue since March 2013.

Elsewhere in the United Rugby Championship, fellow Pool A team Glasgow Warriors were beaten 19-18 at Benetton Rugby. Jack Dempsey and Rory Darge both crossed for the Heineken Champions Cup side, but they went down to a late penalty from the EPCR Challenge Cup contenders.

There was a similar surprise in the Gallagher Premiership, where Pool B side Harlequins lost 22-19 at home to Challenge Cup outfit London Irish, despite Oscar Beard’s brace of tries and a Luke Northmore score.

Meanwhile, Saturday’s TOP 14 action saw Montpellier Hérault Rugby overcome Heineken Champions Cup rivals Castres Olympique 25-24 at GGL Stadium.

Paolo Garbisi’s conversion of Jan Serfontein’s late effort handed Montpellier the win after earlier tries from Jérémie Maurouard and Anthony Bouthier. Kevin Kornath, Geoffrey Palis, Tyler Ardron and Teariki Ben-Nicholas went over for Castres.

Stade Rochelais eased to a 36-8 win at home to Section Paloise thanks to tries from Jules Le Bail, Will Skelton, Jules Favre, Tawera Kerr-Barlow and Ihaia West, while Thomas Ramos kicked all Stade Toulousain’s points in an 18-11 home success against CA Brive, another Challenge Cup side.

It was a different story for Clermont and Stade Français Paris, though. They both lost to Challenge Cup opposition, Clermont 26-24 at USAP despite two tries from Cheikh Tiberghien and one for Tani Vili, and Stade 17-14 at Biarritz Olympique after Telusa Veainu scored their solitary try.
