What happened: Lucas Paqueta is a major doubt for Brazil's scheduled World Cup Round of 16 match against Norway after leaving the Japan match at halftime. Casemiro is expected to be available, while Danilo Santos could replace Paqueta and Vinicius Junior remains central to the attack.

Why it matters: Paqueta's availability will shape Brazil's midfield balance against a Norway side built around Erling Haaland. With Raphinha already unavailable, Brazil have fewer options to alter the attack.

What to watch: Paqueta's fitness and Brazil's confirmed starting lineup are the key developments before kickoff. Casemiro's readiness will also determine the midfield setup.
