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.
Day received a knock on her wrist and while at first it was thought to be a sprain, an X-ray showed that she had in fact fractured a bone.
It is a bitter blow for the talented forward who has worked hard in the last two seasons to gain a place in the Irish Women's squad.
Her place in the panel has been taken by Highfield and Munster prop Laura Guest.
Guest is a secondary school teacher who attended Sacred Heart Clonakilty and University of Limerick. She has been capped nine times for Ireland.
