New York, NY (SportsNetwork.com) - There was one last shuffle of the NBA Playoff seeds Wednesday, with the New Orleans Pelicans and Brooklyn Nets clinching the final two spots.

Half the seeds for the postseason weren't decided heading into the day.

And what a conclusion to the regular season it was.

The Pelicans secured the Western Conference's final playoff spot after defeating the NBA's hottest team, holding on for a win over the defending- champion San Antonio Spurs.

New Orleans, making its first postseason appearance since 2011, will open on the road against the NBA's best Golden State Warriors on Saturday.

The Spurs, unbeaten since losing to the Dallas Mavericks on March 24, would have clinched the West's No. 2 seed with a win. Instead, their loss and victories by both the Houston Rockets and Memphis Grizzlies sent them tumbling to the sixth seed.

San Antonio will clash with the third-seeded Los Angeles Clippers, who concluded their season Tuesday with a rout over the Phoenix Suns. That series starts Sunday.

The Rockets clinched the Southwest Division, which will send all five of its teams to the playoffs. It's the first time every team from one division will compete in the same postseason since 2005-06, when the Pistons, Cavaliers, Pacers, Bulls and Bucks all made it from the Central.

Houston will face the No. 7 seed Dallas Mavericks in the opening round beginning Saturday.

The fourth-seeded Portland Trail Blazers and fifth-seeded Memphis Grizzlies will meet in the final quarterfinal of the West. The Grizzlies will have the home-court advantage in that set because they have a better record. Game 1 is Sunday.

The Nets beat the lowly Orlando Magic and then watched as the Pacers fell to Memphis, helping them clinch the final playoff spot in the Eastern Conference. They will play the Atlanta Hawks starting Sunday, who finished with the East's best mark.

The only NBA Playoff series that was finalized coming into Wednesday was the No. 2 seed Cleveland Cavaliers going up against the seventh-seeded Boston Celtics. Boston went 24-12 over its last 36 games and finished with six straight wins to close the season. They will start their set Sunday.

The Chicago Bulls and Toronto Raptors jockeyed between the third and fourth seeds for the last few weeks, but the Bulls held Toronto off for the No. 3 seed Wednesday after beating the Hawks.

Chicago will square off with the Milwaukee Bucks, who finished 41-41 in Jason Kidd's first year as head coach this season after going a franchise-worst 15-67 in 2013-14. Game 1 is Saturday.

Toronto and the fifth-seeded Washington Wizards round out the East's quarterfinal matchups, with that series commencing Saturday.
