Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Ta'auso suffered a recurrence of a knee injury in the recent 16-3 win over the Dragons, while Muldoon has been ruled out with a groin injury.
Despite missing some of their frontline players, coach Michael Bradley said that his side are looking forward to taking on high-flying Leinster as they aim to build on their win over the Dragons last time out.
"We always look forward to the games against the other Irish provinces and this one is no different as we head into a crucial part of the season," he said.
"Away matches in the Magners League are difficult for everyone. Leinster are European champions, are playing at home and are on the top of league while we are at the bottom.
"Those are the facts, but we don't go into matches thinking about historical reasons why we should or shouldn't win.
"We go into the game with a game-plan and, if we execute it, we are confident we can win it. The fancied team doesn't always win the match - look at Ireland and Scotland last weekend."
