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.
The Lions captain was in attendance for both of Munster's sessions in UL on Wednesday.
O'Connell's non-participation was purely precautionary as he watched his colleagues go through their paces ahead of the clash with the Scarlets.
Speaking about Munster's lead at the top of the league table, Marcus Horan said: "It's ultimately in our own hands at the moment and that's the way we want to keep it. You don't want to be relying on other teams to do you favours.
"The whole squad are well aware of that. It's a nice position to be in, to know that if we just keep winning the league will be ours. But there's a couple of tough games ahead."
On the subject of the title race and Munster's current 11-point lead, forwards coach Laurie Fisher said: "The Ospreys have got a game in hand, so let's give them a bonus point win for that game. There's only six points in it then.
"I think there's still plenty of football to be played. It's far from over."
