San Antonio won its ninth straight; Detroit lost Ben Wallace. Suffice to say it was a much better day for the Spurs than it was for the Pistons.

Tim Duncan had 25 points and 21 rebounds as San Antonio extended the league's longest current winning streak, defeating the short-handed Pistons, 89-83, yesterday in Auburn Hills, Mich.

Wallace went down with a sprained medial collateral ligament in his left knee late in the first half when teammate Tayshaun Prince fell onto him. The all-star, who leads the league in rebounds and blocks, will undergo an MRI exam today to help determine if he will play again this season.

When Wallace limped away from The Palace -- not on crutches -- he was asked how serious he thought the injury was.

"Don't know," he said.

If the news is not good, it will be a crushing blow to the Pistons, who lost their third in a row and dropped a half-game behind New Jersey for the best record in the Eastern Conference.

* LAKERS 115, SUNS 113: Kobe Bryant's jumper with 28 seconds remaining clinched a playoff spot for host Los Angeles and moved the team within 11/2 games of fourth place in the Western Conference.

Bryant, whose jumper as time expired Friday night gave the Lakers a 102-101 victory at Memphis, made the final shot of regulation last night -- a baseline jumper that tied the game with 14 seconds left.

In overtime, Shawn Marion missed a three-pointer with six seconds remaining, and Bryant dribbled out the last few seconds as the Suns tried to commit a foul.

* PACERS 90, HEAT 69: Continuing their recovery from a post all-star break slump, host Indiana closed the third quarter with a 15-0 run and had its best defensive effort of the season to secure the win.

Jonathan Bender scored 15 points and Ron Artest added 13 as Indiana won for the fifth time in six games and moved into third place in the Eastern Conference.

* ROCKETS 114, MAGIC 93: Cuttino Mobley scored 23 points and Steve Francis had 21 as host Houston wore throwback uniforms in a win that counts as Coach Rudy Tomjanovich's 500th career victory.

Tomjanovich is on a leave of absence while undergoing treatment for bladder cancer. Assistant coach Larry Smith is directing the team for Tomjanovich, whose career record is 500-495.

* KINGS 97, 76ERS 81: Sacramento finished 5-1 on a six-game Eastern road trip as Chris Webber had 21 points, 11 rebounds and 8 assists in Philadelphia.

* NETS 96, RAPTORS 87: Kenyon Martin had 24 points and 10 rebounds as New Jersey won on the road.

Vince Carter had a team-high 28 points for the lottery-bound Raptors. Carter left the game with 31 seconds remaining with what appeared to be a sprained left ankle.

* SUPERSONICS 82, JAZZ 80: Rashard Lewis scored 12 of his 24 points in the fourth quarter and made a key three-pointer as host Seattle maintained its playoff hopes.

* TIMBERWOLVES 97, TRAIL BLAZERS 78: Kevin Garnett had 16 points, 14 rebounds and 12 assists as visiting Minnesota closed in on Portland for fourth place in the Western Conference.

Pistons' Ben Wallace is floored after injuring left knee against Spurs in second quarter. He'll have MRI exam today.
