A home victory would see the Scarlets move a step closer to ensuring qualification for next season's Champions Cup and a step closer to securing a top four finish in the Guinness PRO12.
Scarlets head coach Wayne Pivac said; "There will be a lot of intensity in terms of personal battles for Wales jerseys and some thrilling individual match-ups right across the park. We know they're playing very well and scoring a lot of tries. They're trying to get up the table to qualify for Europe.
"From a team point of view it's definitely one game at a time for us. We're in a position where we can control our destiny."
