The NBA is looking into Portland's decision to play a video of Trevor Ariza's flagrant foul on Rudy Fernandez on the scoreboard prior to Friday night's game between the two teams.

The foul took place in a game involving the two teams a few weeks ago.

League spokesman Tim Frank said Saturday that teams are not permitted to show replays involving flagrant fouls from previous games.

"We will be looking into the matter," Frank said.

The Blazers defeated the Lakers 106-98, and could be fined by the league.

"That's something that NBA clubs are not supposed to do, show video before a game that incites crowds," Lakers coach Phil Jackson said. "Portland took a big risk doing that, and that's a finable thing from the league. That's something that they try to prevent in the spirit of good sportsmanship, but Portland has been like that.

They've created that situation, and I think Trevor was affected by it, unfortunately. I don't think he had the kind of game I like to see him have."
