The 2013-14 NBA regular season ends Wednesday, and all 30 teams will be in action on the final night of the 82-game campaign. For 14 squads, it'll offer an opportunity to say so long, farewell, auf wiedersehn and goodbye — until the draft lottery, at least. For the 16 teams that'll enter postseason play this weekend, it offers one more potential pitfall, one last night to survive without incident or injury before loading up for the long, arduous journey to hoisting the O'Brien trophy come late June.

That journey will begin with opening-round quarterfinal matchups, a number of which have yet to be officially determined and will be locked in on the final night of the season. Here's a quick refresher on what's up for grabs and left to play for as we head into the 15-game Wednesday that will set the table for the playoffs.

EASTERN CONFERENCE

• The No. 1 Indiana Pacers, who will have home-court advantage for as long as they're alive in the Eastern Conference playoffs, will take on the No. 8 Atlanta Hawks.

• ... That's it.

WESTERN CONFERENCE

What's at stake on Wednesday

EASTERN CONFERENCE

• The Toronto Raptors can secure the No. 3 seed by beating the New York Knicks at Madison Square Garden. Even if they lose, they can still finish third if the Chicago Bulls lose their road game against the Charlotte Bobcats.

• If the Raptors lose the Knicks and the Bulls beat the Bobcats, Chicago finishes third and Toronto finishes fourth. If both teams win or both teams lose, the Raptors end up in the No. 3 spot by virtue of winning the Atlantic Division, pushing the Bulls down to the No. 4 seed.

• The Brooklyn Nets can sew up the No. 5 seed by beating the Cleveland Cavaliers.

• If the Cavs win, the Washington Wizards can overtake Brooklyn for fifth place by beating the Boston Celtics at TD Garden.

• If the Nets win, the best Washington can do is No. 6, which they can secure by beating the Celtics.
