It's been a highly contested affair in Thomond Park.
There hasn't been much to separate these two teams, often is the case when Ulster and Munster meet.
Ulster are looking for a much-needed victory to get their play-off ambitions back on track.
While Munster want to confirm their home semi-final as soon as possible so they can fully concentrate on Saracens next weekend.
Both sides named really strong XV's which has led to the tight nature of today's proceedings.
Ulster got off to a great start through a Rory Best try before Angus Lloyd responded almost straight away for Munster.
The Lloyd score was characterised by a brilliant Peter O'Mahony dummy.

The match boiled over on a number of occasions as both sets of players engaged in off the ball tussling, probably best described as handbags.
It was nothing too serious though but Simon Zebo had a very interesting opinion on what was taking place on the field.
Zebo was wearing the Sky Sports player mic so we got a chance to listen to what the Cork man was saying on the pitch.
Once there was a break in the game, Zebo seemed to give his opinion on the Ulster players' physical approach to the game to referee, Marius Mitrea.
"They're watching too much UFC!"

Brilliant.
