Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Prop Botha, who sustained a knee injury in Munster's pre-season game against London Irish, has displayed great commitment to the rehab programme set out by the medical staff in getting match ready for the round five fixture.
Head coach Rob Penney has opted to start the fit-again Felix Jones at full-back on Saturday, with Keith Earls switching to the right wing as Casey Laulala and James Downey resume their centre partnership.
With the return of 2013 Lion Murray, Cathal Sheridan misses out this week with Duncan Williams starting alongside Ian Keatley at half-back.
Stepping up for his first start of the season, Paul O'Connell joins Donnacha Ryan in the second row pairing, while young captain Peter O'Mahony, Niall Ronan and James Coughlan form the back row.
