That hurdle overcome, and registered for European action, Puafisi will start on the bench for Sunday's game against Edinburgh, the second of the back to back games between the two teams.
Gloucester produced an efficient performance to take the spoils at Murrayfield last Sunday, and will now be looking to complete the job and follow up with victory at Kingsholm.
Munster currently lead pool 6 by two points from Gloucester so, with Munster travelling to Perpignan, it's very tight at the top of the pool.
Previewing the fixture with the local media this week, Director of Rugby Nigel Davies admitted that he's expecting a reaction from Edinburgh this weekend.
"To go to Edinburgh and get a result was very significant in the context of our season. It's a very difficult place to go, I've experienced that in the Celtic League in the past.
"Obviously in this competition, they've already taken the scalp of Munster so they're a very capable outfit and, certainly from their reaction after the game on Sunday, it was a game they expected to win.
"But we played some good rugby and it was one of our most comfortable wins for a while in all fairness. They did start to put some pressure on us in the second half, but we held out in a couple of key moments.
"They're a very competent side, and they'll no doubt use the disappointment of last weekend to come down here, put in a big performance and get a result back. We have to be very wary of that."
