He takes over in midfield from Ian Whitten who has dropped down to the replacements bench.
Stephen Ferris is also back in the number 6 jersey, after recovering from the ankle injury which kept him out of the Leinster game last weekend.
In the third personnel change, Ed O'Donoghue replaces the injured Dan Tuohy in the second row.
Commenting on Ulster's final Magners League game before the break for the autumn internationals, head coach Brian McLaughlin said: "You've always got to be wary of Munster. When you think of what has happened to them in the past month, they are going to want to get back on track.
"They are playing at Thomond Park, where they're extremely strong, so we are under no illusions about what we're going to face down there.
"It will be a very confrontational full-strength Munster side, so it's going to be a very hard game.
"We just have to concern ourselves with going down there with the right attitude, playing with the confidence we have been and looking for a good performance.
"It's going to be a good check for us. It's going to be a good place to go, take them on and test ourselves."

"There's no crisis in the camp, there's no panic. This is as good a squad as I've been involved with.
