The second half started much like the first half ended – with plenty of action.
It's 3-2 after Swiss midfielder Remo Freuler scored a brilliant goal in the 48th minute. It was a team goal, set up by a flick pass from Reuben Vargas.
The boisterous Serbian fans have fallen a bit quieter as they nervously watch their team in need of two goals to advance in the tournament.
While action can be expected from both sides in this match, it is absolute table stakes for Cameroon to bring more 🔥 to their game, overcome the Seleção defense, and score some goals if the team wants to stay in contention for a spot in the knockouts.
Brazil has kept the ball and made more attempts on Cameroon's goal, but have not yet scored an opener.
At the moment, things stand at 0-0 for both teams.
The teams are back on the pitch for the second half at Stadium 974 in Doha, Qatar.
What's in store? More goals, quite possibly, based on what we saw in the furious first 45 minutes of play.
While Switzerland can potentially advance to the knockout stage even with a draw, it is hoping for an outright win, which would guarantee a trip to the Round of 16.
Serbia is under even greater pressure. It must win for any shot at moving on.
An exciting first half has drawn to a close with Serbia and Switzerland deadlocked at 2-2.
Serbian Dušan Vlahović, a star striker who's playing injured, scored his first World Cup goal to help his side pull ahead 2-1. But Switzerland was quick to answer shortly before halftime.
It's been a truly even matchup — the two sides have split time of possession roughly equally. Serbia has three shots on goal to Switzerland's five.
Neither side can afford to lose this match if they want to move on to the knockout stage.
A thrilling second half is likely in store.
A very uneventful first half between Brazil and Cameroon has ended. At halftime, both teams are in a scoreless tie.
Brazil might not need a goal, but Cameroon certainly does if it want to remain in contention for a berth in the Round of 16. So far, though, the Indomitable Lions have only amassed three yellow cards against Brazil's one.
The Seleção have dominated ball possession and made 10 attempts at Cameroon's goal but frustratingly, they have failed to capitalize on each opportunity.
Let's hope that at least one team returns in the second half with some fireworks to display.
The goals keep coming in Switzerland vs Serbia – with the Swiss getting an equalizer in the 44th minute.
This time it was forward Breel Embolo who found the back of the net.
Serbia has scored again, pulling ahead in a match against Switzerland that neither side can afford to lose.
It's 2-1 in the 35th minute after the goal from Dušan Vlahović.
The striker's score is all the more impressive as Vlahović has been nursing a groin injury.
Serbia just tied it up with a goal of its own, making it 1-1 against Switzerland in a must-win clash between teams in Group G.
Aleksandar Mitrović scored with a brilliant header in the 26th minute, a swift answer to an opening goal from the Swiss.
Mitrović, who is a striker for Fulham in the Premier League, now has eight goals in his last seven matches for Serbia and 52 goals in just 79 international appearances.
Switzerland struck first in its match against Serbia, making it 1-0 in the 20th minute.

Shaqiri also scored against Serbia in the 2018 World Cup.
