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 Ulster Rugby ground staff are working around the clock to try to ensure a playable surface and safe venue for spectators come Monday.
At this stage the game is still scheduled to go ahead. Please keep checking the Ulster and IRFU websites for updates over the festive period.
