Cymru will play a home game in front of supporters for the first time in 20 months, when they face Albania at Stadiwm Dinas Caerydd at 17:00 today.
A crowd of 6,500 will be present at the 33,338 capacity stadium.
Neco Williams will miss the fixture after receiving a red card in Wednesday's game against France.
Cymru will kick off their Euro 2020 campaign against Switzerland on Saturday June 12.
They also face Turkey on Wednesday 16 June, and Italy on Sunday 20 June.
Cymru captain Gareth Bales said: "As long as it's done safely and correctly, we'd love to see that.
"Seeing things when we're over [abroad] in the tournament, looking back and seeing pictures, videos being sent is always nice to see.
"Obviously we won't have that atmosphere in the stadium but to see it back home will feel like that extra support that we always get and it will be nice for the fans to get together and watch these big games and enjoy the occasion."
