Brazilian officials are inaugurating the Arena da Amazonia in the jungle city of Manaus, the ninth World Cup stadium to become available for soccer's showcase event. Three still have to be finished, including the one hosting the opener in Sao Paulo in about three months.

The Arena da Amazonia won't be fully completed Sunday, but local authorities are inaugurating the venue with a regional championship match that will have 20,000 people in attendance, including workers who helped build the venue.

The 44,000-capacity stadium will host four World Cup matches in June, including England vs. Italy and United States vs. Portugal.

The Arena da Amazonia was one of the six stadiums that were not completed by the end of last year as wanted by FIFA.
