How To Watch Leinster Rugby vs. Harlequins Free Stream

A decade of Champions Cup disappointment could be coming to a close if the lads from Dublin have their way, while another group from Twickenham would like nothing more than to pile on what has been a strange season for Leinster Rugby.

A 3-0-3 record in the United Rugby Championship for Leinster Rugby almost reads like a typo for the most dominant club team of the last five years — but one that has only a URC Grand Final win to show for it.

Dominated by Irish internationals, Leinster saw most of its players suit up for the British and Irish Lions or the Irish national team this summer. That left a somewhat depleted squad to start the season.

Still, arguably the deepest club in the world probably should have played better in South Africa against DHL Stormers and Vodacom Bulls squads missing their Springboks.

However, since starting the season 1-3, Leinster has won back-to-back matches against Zebre Parma and, most recently, against the Dragons in Wales, 24-10.

Harlequins, meanwhile, also has muddled through international roster issues and is 2-0-4 in Gallagher PREM Rugby play. Armed with star Marcus Smith, the Quins are talented enough to go to Dublin in Round 1 and win at the Aviva Stadium at 12:30 p.m. ET on Dec. 6.

The Quins certainly are not as favored to win Pool 3, as Leinster is, but the match matters for the race to the Round of 16.

The Quins, like Leinster, avoid traveling to South Africa to play the DHL Stormers and get Bayonne at home. It could all set up a massive match at La Rochelle in Round 4.

But an upset against Leinster in Dublin would change the math for everyone.

This match is streaming live on FloRugby and the FloSports app. The match also will stream for free on the FloRugby YouTube page as part of the 12 Days of Christmas presented by World Rugby Shop.
