The eighth-place Bulls lead Toronto by a game in the Eastern Conference and will make the playoffs as long as they finish with a better record, meaning they need a win at Charlotte on Wednesday or a loss by the Raptors to New York.
Fourth-place Boston, meanwhile, can forget about catching Atlanta for the third seed after falling for the sixth time in nine games.
Paul Pierce led the Celtics with 28 points, and Ray Allen scored 25. Kevin Garnett added 14 points and nine rebounds after sitting out the previous game to rest.
Lakers 106 Kings 100: In Los Angeles, Pau Gasol had 28 points and eight rebounds, Shannon Brown scored 24 points and Kobe Bryant rested as the Lakers finished their regular-season home schedule.
Sasha Vujacic scored 13 points for the Lakers, who lost six of nine before Gasol and the reserves pulled away in the second half for their sixth straight win over the Kings.
Tyreke Evans scored 10 points before his remarkable rookie season ended with a third-quarter ejection as the Kings wrapped up their fourth straight losing season.
Bryant sat out to rest his litany of injuries, including a sprained ankle and a broken finger, while center Andrew Bynum missed his 12th straight game with a strained Achilles' tendon. Both starters should be ready to play this weekend in the playoffs.
Suns 123 Nuggets 101: In Phoenix, Amare Stoudemire scored 26 points and Steve Nash had 18 points and 10 assists before sitting out the fourth quarter as the Suns clinched homecourt advantage in the first round of the playoffs.
The Suns made 14 of 24 3-pointers, 11 of 17 in the first three quarters. Phoenix jumped to an 18-2 lead and the Nuggets never cut it to single digits after the first quarter.
The Suns can finish no worse than No. 4 in the West and would be No. 3 if they win at Utah on Wednesday night. Denver, which finished its regular season, would get the No. 4 spot and a first-round homecourt edge if Phoenix beats the Jazz.
Carmelo Anthony scored 29 and Chauncey Billups had 16 in the Nuggets' 11th straight loss in Phoenix.
Jazz 103, Warriors 94: In Oakland, Calif., Mehmet Okur had 23 points and seven rebounds, Paul Millsap grabbed a career-high 24 rebounds and Utah swept the three-game season series against Golden State.
The Jazz' Carlos Boozer strained his right ribcage while playing all 12 minutes of the opening period. He was taken to the locker room for X-rays at the start of the second quarter but didn't return.
The Jazz wrap up the season Wednesday night at home against Phoenix in a game that will determine both teams' playoff seedings. Utah, riding a 10-game home winning streak, could be as high as the No. 2 seed or fall to fifth.
Devean George scored a season-high 21 points off the bench for the Warriors.
