Fan's filing of report draws review by league

DALLAS -- It has to be the leading candidate for Best Game of Round 1: Dallas 118, Golden State 112. So what could spoil the mood heading into Thursday's massive Game 6?

League discipline, of course.

There are a few situations to monitor after Tuesday's roller-coaster Game 5 of the Warriors-Mavs playoff series. And an NBA spokesperson told ESPN.com that all three incidents are under review.

" NBA observers in the building interviewed multiple spectators after the game about an alleged tangle between Golden State's Jason Richardson and a Mavericks fan sitting across from the Dallas bench. Richardson fell after a shot and tempers appeared to flare when the Warriors' swingman felt he was being impeded as he tried to get up to rejoin the game. Because the Mavs fan filed a report with NBA security, league officials are expected to review the incident.

" Golden State's Stephen Jackson was ejected with 8.9 seconds to play to make it two ejections for Jackson in the Warriors' two losses in the series. Jackson maintains he was unfairly expelled this time for clapping -- the same offense that got Baron Davis ejected from their 112-99 Game 2 loss -- but it remains to be seen whether the league plans to tack on a penalty in addition to Don Nelson's postgame vow to fine his primary Dirk Nowitzki defender "a substantial amount."

NBA commissioner David Stern said Friday in Oakland, after Jackson was fined $50,000 for his first ejection and mostly for not leaving the court in a timely manner, that Jackson's past transgressions didn't factor into the punishment.

"But the next one will," Stern added.

" There's also the matter of Dallas' Jason Terry shoving Baron Davis near the Warriors' bench. The incident might get a review from the league as well, since it received plenty of TV time postgame.
