The United Rugby Championship returns this weekend, and it's a mouth-watering clash as second-placed Ulster make the short trip to Dublin to take on the current table-toppers and interprovincial rivals, Leinster.
Teams will be announced on Friday at 12 noon.
The Ulster men have some huge games coming up at Kingspan Stadium, starting with the eagerly anticipated Heineken Champions Cup tie against Northampton Saints on Friday 17 December.
Over the festive period, Ulster will have two home interprovincial derbies against Connacht and Leinster on Boxing Day and New Year's Day respectively.
Then, on Saturday 22 January, French giants ASM Clermont Auvergne are in town for the potentially curcial final Champions Cup pool stage game.
