Cardiff hosts the Scarlets at Arms Park to renew the historic Welsh derby.

With Cardiff representing the capital city, and the Scarlets carrying the pride of west Wales, this regional clash extends far beyond the scoreboard. A win means more than just rugby.

Cardiff’s physicality meets the Scarlets’ unpredictable attack on Dec. 19. From the 2:45 p.m. ET kickoff, fans can expect a hard-fought, high-intensity contest.

Though Cardiff seems to be a stronger team this season, the Scarlets have won four of their last four meetings, though the winner has been decided by fewer than 10 points each time.

Cardiff has been dominant in URC play, dropping just one of its six matches so far and coming off a victory in its most recent league outing.

The Scarlets have endured a tougher start, with only one URC win to date. That victory, however, came against Glasgow, which recently defeated Toulouse and sits firmly at No. 5 in the standings. The Scarlets have shown flashes of potential, but consistency has been elusive.

This matchup will reveal whether rivalry energy can unlock another level for the Scarlets, or if Cardiff continues to build momentum at home.
