Joint-captain Rob Herring marked his 100th cap for the province with an eleven-point win
Ulster lead the Pro12 after three wins in a row to start the season.
They beat Scarlets 19-8 last night, with tries from Louis Ludik and Iain Henderson.
Man of the Match Paddy Jackson scored nine points with his boot, on his return to the side.
Speaking to Q Radio Sport, Jackson says the win was a nice way to mark joint-captain Rob Herring's one hundredth cap for the province.
