They face a Scarlets side who are just four points behind them in the table and missing just three of their international, Stephen Jones, Matthew Rees and George North. Besides that the Welsh side are enjoying a rich vein of form and last weekend accounted for London Irish comfortably in the LV Cup.
Scarlets coach Nigel Davies does not anticipate a stronger challenge on Sunday. "We know it's going to be a difficult place to go. They had a massive win on Tuesday against the Australians but this won't be a bigger one than last week when we came through against a strong London Irish side."
The five day turnaround is certainly something that could be a factor because that clash with the Wallabies was a hugely physical affair and in the conditions energy sapping but it would also have provided a massive boost to the morale of the squad.
Murphy returns to the Munster starting line-up for the first time in over a year. He's had a few outings with his club UL Bohs, got a few minutes off the bench on Tuesday and has looked particularly sharp in training this week.
Other than that the backline remains the same as Tuesdays while the inclusion of Quinlan is the only change up front in a side that will be captained by Doug Howlett.
