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.
Speaking about Fitzgerald's fitness and Fergus McFadden who has a hamstrain strain, scrum coach Greg Feek said: "Ferg's not too far away, while Luke is probably closer. We#ll see how Luke goes this week.
"He's not looking too bad. Look, with the history, I suppose we're just monitoring him. We've got really good medicals and rehab (facilities) here. With the protocols in place, we#ve just got to make sure he#s ready and firing to go."
Winger Darren Hudson suffered a hamstring injury during the drawn game against the Ospreys last Saturday night and will not play this week.
Kevin McLaughlin made his first appearance of the season alongside the likes of fellow Ireland internationals Ian Madigan and Richardt Strauss.
Last Saturday's match marked Jack McGrath's 40th in Leinster colours, while both McFadden and McLaughlin have now made 96 appearances for their home province. Mike Ross' next outing will be his 90th for Leinster.
