It's Rangers' deepest European run for 14 years and tonight we will find out if they are likely to extend it even further.
The Ibrox side are in Portugal to face Braga, a team they know well having defeated them home and away back in 2020 under Steven Gerrard.
That wasn't as easy a tie as it sounds with Rangers having to come back from two goals down at Ibrox.
Ianis Hagi was the inspiration that night but he's missing this time, joined by injured talisman Alfredo Morelos.
Fans will be on tenterhooks to see how the match plays out, but if you want to see the game, your options are fairly limited.
Where can I watch Rangers' match with Braga?
You can only watch it on BT Sport in the UK.
The game is on the BT Sport 2 channel.
Coverage starts at 7.15pm with the game kicking off at 8pm.
How can I get BT?
You can subscribe via a TV service like Sky or Virgin.
What about online?
BT allow you to pay a £25 fee with no contract to watch a month of action.
The pass gives you all the BT Sport channels. While it sounds a lot, it would also cover you for the second leg AND the semis if Rangers get that far.
You can watch on your Smart TV, tablet, laptop, desktop or even your phone.
Can I get the game through Rangers TV?
Yes you can, but only if you are not based in the UK.
