Rangers fans expected to be going to Armenia with this one already in the bag after the first leg.
It didn't quite work out that way in the first leg as the 10 men of Rangers needed a second half goal from Alfredo Morelos to claim a win.
John Lundstram was sent off and will be missing from Thursday night's game, as will Kemar Roofe who serves the final game of his suspension.
Others are set to be out now too after Covid-19 issues with the club confirming cases on Tuesday night.
It's unclear exactly who will be missing due to the virus but Rangers and Steven Gerrard will still be expecting a good win ahead of Sunday's Old Firm clash at Ibrox.
And here's all you need to know about the match.
Where and when is the game taking place?
The match is at Republican Stadium on Thursday, August 26.
Kick-off is at 4pm.
Is it on TV?
Yes. The game will be shown live on BBC Scotland.
Will there be a live stream?
Yes. Supporters will be able to watch the game live on the BBC iPlayer if they are unable to get in front of a TV.
Who is the referee?
Tobias Stieler is the man in the middle for this one.
The German ref will be assisted by Christian Gittelmann and Eduard Beitinger and Harm Osmers.
The German ref has been in charge of two games this season and has dished out eight yellows and a red, and all of those came in one game.
Prediction
Rangers look to be getting back into form but the weather and travel will have a say in this one.
It's unclear exactly who will be missing because of the Covid-19 issues at the club but you'd still expect Rangers to win.
Prediction: Alashkert 0 Rangers 2
