Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Having played 93 times for Ireland and earned six Lions caps, Sunday's game will mark O'Driscoll's 100th Test match.
At half-back, Ronan O'Gara will earn his 93rd cap for Ireland and will be partnered by Tomas O'Leary.
Up front, young prop Cian Healy will pack down at loosehead alongside Jerry Flannery and John Hayes, making his first start in an Ireland senior jersey.
There are two other uncapped players in the squad with Sean Cronin named as replacement hooker and Jonathan Sexton as cover at out-half.
In all, there are two changes to the side that secured Ireland's first Grand Slam in 61 years against Wales last March, with Wallace and Healy coming in for Gordon D'Arcy and Marcus Horan.
