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 IRFU will be requesting that all clubs and representative teams playing matches at the weekend observe a minute's silence before kick-off and fly their club flag at half mast.
In addition, the naming of an Ireland squad for a training camp that is due to take place from next Sunday to Tuesday has been postponed until later this week.
Meanwhile, as a gesture of support, fans from the other provinces are hoping to give their own renditions of 'Stand Up for the Ulstermen' during their league games next Friday and Saturday.
