The National Basketball Association is investigating an incident during last Saturday's Mavericks-Trail Blazers basketball game.
The incident happened less than two weeks before All-Star weekend activities, so of which will take place in the arena. Security is expected to be tight for those events.
"We're looking into exactly what happened," Tim Frank, the NBA's vice-president, basketball communications, said in an e-mail to the Oregonian on Wednesday. The women were reportedly allowed to return to their seats and were not kicked out of the arena.
The incident took place with 41 seconds left in the game.
