Cameroon don't deserve to go through with this performance.
Serbia 2-3 Switzerland
Another yellow card, this time to Fabian Schar for barging into Strahinja Pavlovic.
Serbia's free-kick is cleared.
Cameroon 1-0 Brazil
It's almost full time and Cameroon are on the verge of a famous win. It may not be enough to go through but beating Brazil is no easy feat.

Josh: If you're going to go out THAT is how you go out. Aboubakar with a thumper. The high five from the referee while giving the second yellow was fantastic too.

Into the final minute.
Serbia need to get the ball forward but they can't get hold of it at the moment.
Switzerland are nearly there...
Cameroon 1-0 Brazil
There's four minutes left and the Cameroon celebrations in the stands have turned to nervous glances at phones. They need a helping hand in the other game.
Serbia 2-3 Switzerland
The excellent Breel Embolo exits to a standing ovation from the pocked of Switzerland fans inside Stadium 974.
Salzburg man Noah Okafor comes on for the last few moments.
That goal changes nothing, BUT...
Cameroon will qualify if Serbia equalise and the African side beat Brazil by at least two goals.

Uh-oh. A poor end to a very good game as it's kicking off with Granit Xhaka and Nikola Milenkovic involved.
Serbia goalkeeper Vanja Milinkovic-Savic actually helps Xhaka out by standing in front of him to block him from retaliating.
Blow the whistle, referee!
Serbia 2-3 Switzerland
Tempers spill over again as Nikola Milenkovic shoves Granit Xhaka in the chest, which sparks a melee involving players from both sides.
Xhaka is booked, as is Milenkovic.

That's one of the dumbest things I've ever seen. I can understand his excitement but he has to keep his emotions in check. Now he's been sent off.
Cameroon 1-0 Brazil
But then the goalscorer is sent off as he is shown a second yellow card for taking his shirt off to celebrate.
It is a huge goal but Cameroon still need a Serbia goal in the other game.
Could we be on for more late drama?

He's been absolutely hopeless all evening but what a header.
Serbia 2-3 Switzerland
Luka Jovic loops a tame header over the crossbar. It wasn't troubling Gregor Kobel.

OH MY GOODNESS ME.
Serbia 2-3 Switzerland
Switzerland break forward through Christian Fassnacht but Serbia are back in numbers and the Young Boys player is forced to play the ball back into midfield.
It's just about game management for Switzerland now.
