Tite made nine changes to his team after Brazil defeated Switzerland to advance to the round of 16, which led to a fragmented Selecao performance at the Lusail Stadium.
Devis Epassy made several excellent saves to keep Cameroon in the game, but Aboubakar nodded in a victory in stoppage time for Rigobert Song's team. Aboubakar was then given a second yellow card for taking off his jersey.
The outcome, however, was ultimately unimportant because Switzerland narrowly defeated Serbia 3-2 in the group's second match, guaranteeing Brazil would win the pool and eliminate Cameroon.
