The three-time defending champion Los Angeles Lakers have a record of 0-2 - 29th best among the 29 NBA teams.

Losing for the second time in as many nights, the Lakers also got a scare Wednesday when Kobe Bryant took a hard fall in the first half and sat out for several minutes. Bryant returned and had 25 points, but Los Angeles lost 102-90 at Portland.

Of the five teams that have already played two games, the Lakers are the only one with an 0-2 record.

In other games, Chicago beat Boston 99-96, Indiana beat Houston 91-82; Toronto defeated Washington 74-68; Philadelphia edged Milwaukee 95-93; New Jersey beat Atlanta 105-94; Orlando beat Miami 100-86; Detroit beat New York 86-77; Dallas beat Memphis 119-108; Minnesota beat Denver 83-77; New Orleans beat Utah 100-75; Cleveland hold off the Los Angeles Clippers 98-96; Golden State beat San Antonio 106-98; and Seattle beat Phoenix 86-73.

The Blazers took advantage of Bryant's brief absence, turning a 3-point deficit into a 17-point lead. The Trail Blazers built their lead as high as 23 when Rasheed Wallace put the Blazers up 77-54 with a 3-pointer late in the third quarter.

This is the first time since 1990 the Lakers have opened a season with two losses. Only six teams in NBA history have started the season 0-2 or worse and still won a title.

"It's good for us," Jackson said. "We're going to have to look at that situation (without O'Neal and Rick Fox) for a while and deal with it."

Bulls 99, Celtics 96

At Boston, Trenton Hassell scored eight points in the final 3 minutes, including a pair of 3-pointers.

Hassell scored 14 and Jalen Rose had 21 points and 12 assists for the Bulls, who won despite poor free-throw shooting from rookie Jay Williams down the stretch.

Raptors 74, Wizards 68

At Toronto, Morris Peterson scored 20 points, and Michael Jordan went scoreless in the second half and even missed a dunk.

Jordan scored just eight points in 25 minutes off the bench. After missing two free throws with 4:06 left, he missed a breakaway dunk as the ball clanged off the back rim. The crowd laughed at Jordan, who turns 40 in February, and the Wizards, down by 12, never recovered.

76ers 95, Bucks 93

At Philadelphia, Allen Iverson had 28 points, including a go-ahead jumper in the final minute.

Aaron McKie had 18 points, Keith Van Horn added 16 and Todd MacCulloch had 10 points and a career-high 14 rebounds. Ray Allen scored 28 points for Milwaukee, but missed a long jumper and turned the ball over in the final minute.

Nets 105, Hawks 94

At East Rutherford, N.J., Jason Kidd had 16 points, 12 assists and eight rebounds, taking over in the closing minutes after the Hawks cut a 17-point lead to 96-92.

It was a hectic end to a season opener that saw the Nets raise conference and Atlantic Division championship banners - their first since joining the NBA in 1976.

Magic 100, Heat 86

At Miami, Orlando improved to 2-0 for the first time since 1993, taking advantage of Miami's sputtering offense and defensive breakdowns to spoil the Heat's season opener.

Tracy McGrady scored 24 points and Grant Hill added 17 for the Magic, who shot 55 percent - including 8-for-12 from 3-point range.

Pistons 86, Knicks 77

At Auburn Hills, Mich., Richard Hamilton scored 22 points in his Pistons debut and Detroit's depth wore down injury-depleted New York.

Allan Houston scored 31 and helped New York lead by as many as 12 in the first half, but Detroit scored 15 straight points midway through the fourth - capped by three straight 3-pointers by Chucky Atkins.

Mavericks 119, Grizzlies 108

At Memphis, Tenn., Steve Nash scored 24 points, Michael Finley added 21 and Dirk Nowitzki had 20 points and 11 rebounds.

Gordon Giricek finished with 29 points for Memphis. Pau Gasol had 27 points and 10 rebounds despite playing with his left hand heavily wrapped to protect a sprained wrist.

Timberwolves 83, Nuggets 77

At Minneapolis, newcomer Troy Hudson scored 23 points and Kevin Garnett added 13 points and 12 rebounds for the Timberwolves, who held off a rally.

The loss spoiled the debut of Nuggets coach Jeff Bzdelik.

Hornets 100, Jazz 75

At New Orleans, Baron Davis had 21 points and 10 assists in front of a standing-room only crowd of 17,668 as the Hornets played their first game in their new home.

Jamal Mashburn added 16 points and nine rebounds, Courtney Alexander scored 19 off the bench and David Wesley added 15.

Cavaliers 98, Clippers 96

At Los Angeles, Zydrunas Ilgauskas hit a turnaround 10-foot jumper with 2.8 seconds remaining.

Ricky Davis scored 25 points, Ilgauskas had 19 and Tyrone Hill added 17 points and 13 rebounds for Cleveland, which lost by 27 at Sacramento a night earlier.

Warriors 106, Spurs 98

At Oakland, Calif., Antawn Jamison scored 36 points on 14-of-25 shooting and Jason Richardson added 22 in Eric Musselman's head coaching debut.

Richardson also had eight rebounds and eight assists. Tim Duncan had 24 points and nine rebounds for San Antonio, which looked sluggish after beating the Lakers on Tuesday night to start the season.

SuperSonics 86, Suns 73

At Seattle, Brent Barry had eight of his 25 points in the fourth quarter and Gary Payton scored 20.

Barry shot 9-of-12, including 5-of-6 from 3-point range. Shawn Marion had 21 points and 11 rebounds as the Suns lost their opener for the fourth straight year.
