Scotland will take on Georgia at the BT Murrayfield Stadium in Edinburgh on Friday 23rd October. The match has been scheduled to act as a warm-up for the Scots ahead of their final Six Nations fixture the following week. Scotland has won all four encounters with the Lelos. Scotland and Georgia met twice last year in Rugby World Cup warm-up games, with the Scots winning 44-10 in Tbilisi at the end of August then 36-9 at Murrayfield a week later.
The WRU says it still has options in place to play the two remaining Autumn Nations Cup matches against England on 28 November and the play-off final fixture on 5 December in London, in order to maximize potential revenue.
But that will depend on whether the UK Government allows fans to attend sporting events in England, with plans for crowds from October 1 postponed this week due to rising cases of Covid-19.
"Given how vital Wales games are to the funding of our sport, it was only right that every option was explored," said chief executive Phillips.
"More important than that is the health of supporters, players and the nation as a whole and so, whilst making contingency plans, we have of course been conscious of following government advice closely every step of the way.
"We anticipate the two games will take place behind closed doors. However, if the big picture changes we would be open to exploring whether either game could serve as a test event for crowds."
No games this year can be played at Principality Stadium in Cardiff as this venue is still in use as the Dragons Heart Hospital. However, if future Welsh or UK Government health and safety guidance allows for some supporters, the WRU has not ruled out taking the two final matches on the road.
"We hope supporters will understand we are duty-bound to continue to explore all options before making a final call with respect to England and the Autumn Nations Cup final match," added Phillips.
"We are hopeful it will be deemed safe for at least some, perhaps socially distanced and restricted, crowds to attend these matches and also remain open to the prospect of using the Parc y Scarlets fixtures as test events with limited attendances if possible.
"Whilst it is disappointing to play these matches without supporters we would like to thank all of those who follow, support, and participate in Welsh rugby and our partners for their patience during these hugely challenging times."
The WRU had always hoped to stage three games in London for financial reasons but no return date has been set for the return of crowds in England, with prime minister Boris Johnson warning that new measures could be in force for up to six months.
Wales kick off their autumn program with an away trip to face France on 24 October before the Scotland game seven days later.
Wayne Pivac's side is scheduled to travel to Ireland in the Autumn Nations Cup on 13 November, before hosting Georgia and England in pool matches. Finishing positions in the two pools will determine fixtures in the final round, with Wales due to face France, Fiji, Italy, or Scotland.
Wales is then due to host England and Ireland in the 2021 Six Nations in February and March and will hope the tournament is not held behind closed doors.
Departing WRU chief executive Martyn Phillips said earlier this year they could lose £50m of revenue if Wales does not host autumn internationals and 2021 Six Nations games.
The WRU's group income in the 2018-19 financial year was £90.5m - with half of that, £44,5m, coming from Principality Stadium match income. More details of International Rugby match Scotland vs Georgia Live Stream Online
