The World Cup stadium in the southern Brazilian city of Porto Alegre held its first test event Saturday, an important step before it's finally handed over to FIFA for soccer's showcase event.

Brazilian club Internacional opened the Beira-Rio in a match against Caxias in a regional tournament, allowing 10,000 of its fans to attend. The stadium will hold 50,000 people, but authorities will not authorize the sale of all tickets until the work is fully finished.

The Beira-Rio is one of the five stadiums yet to be finalized just four months before the World Cup, although work is advanced in and outside the venue.
