Davidson’s appointment, along with that of Joy Neville as the Television Match Official for the fixture in Ireland, means it will be the first time in a top tier professional rugby clash that a match has featured a female referee and TMO.
This all adds to a final official round where the focus will be on European Cup places and a chance for the two finalists to consolidate their game plans ahead of the Cup showdown.
In Conference A, Ospreys will secure third spot should they beat group winners Leinster, but defeat opens the door for Glasgow Warriors ahead of Sunday’s potentially crucial clash with fourth-placed Dragons.
Things don’t look great for the Ospreys though, as they are on a three game losing streak after defeats to Ulster, Dragons and Glasgow in the past three weeks, and they have not won their last four outings against Leinster.
In fact, the last time Leinster lost to a Welsh side was two and a half years ago and unless Ospreys can find some inspiration it may well be more of the same.
That may leave the door open for Glasgow, who head to Cardiff looking for a third consecutive victory and a chance to secure third spot in the conference.
Conference B is just as tight, with the Scarlets needing to beat Connacht on Monday night to seal the crucial third spot but face some pressure from Cardiff Blues who face a resurgent Edinburgh at the same time with Cardiff just three points behind.
Scarlets have won their last two encounters against Connacht, who have already secured the runners-up spot in Conference B, and know the Irish side has not won in Llanelli for almost 16 years.
Edinburgh still have a mathematical chance of qualifying for the European Cup with two games in hand over Cardiff and Scarlets.
While this is the final official round, next week will still see games as teams catch-up postponed fixtures that were forced to be cancelled due to the COVID-19 pandemic.
Edinburgh will be buoyed by the fact they beat Cardiff in their last three games, while the added pressure of European qualification will weigh heavily on all three teams.
Munster and Ulster will be looking for some confidence-boosting victories when they travel to Italy to take on Benetton and Zebre respectively.
