Knicks 100, Heat 76

MIAMI – The Miami Heat lost at home for the third game in a row Friday night, and they’ll have to shake their slump without Shaquille O’Neal.

Reserve Jamal Crawford scored 19 points, and the New York Knicks took advantage of O’Neal’s absence to beat the defending NBA champions 100-76.

The Heat announced shortly before tipoff that O’Neal, sidelined since Sunday, will undergo surgery for torn knee cartilage and be out four to six weeks.

It’s a familiar pattern for the Heat: Last season, O’Neal sprained his ankle in the home opener and missed the next 18 games.

Cavaliers 92, ‘Wolves 76

CLEVELAND – LeBron James scored 37 points and Zydrunas Ilgauskas matched a season high with 14, leading the Cleveland Cavaliers to their fifth straight win, 92-76 over the Minnesota Timberwolves on Friday night.

James added nine rebounds and six assists for the Cavs, playing their first game without guard Larry Hughes. He sprained his right ankle on Wednesday against Portland and could miss several games.

It’s a significant loss, but the Cavaliers are used to not having Hughes around. He missed 46 games with a broken finger last season, but Cleveland managed to go 27-19 while Hughes was sidelined.

Kevin Garnett scored a season-low 14 on 5-of-17 shooting and rookie Craig Smith 12 for the Timberwolves, who scored only 31 points in the second half and lost for the fifth time in six games.

MEMPHIS, Tenn. – Dirk Nowitzki scored 26 points, Erick Dampier added 22 points and 15 rebounds, and the Dallas Mavericks beat the Memphis Grizzlies 115-103 Friday night for their fourth straight victory.

He was 8-of-11 from the field, many of them on dunks or second-chance points, sending the Grizzlies to their sixth straight loss. The win puts the Mavericks at .500 for the first time this season. Nowitzki shot only 3-of-13 from the field in the first three quarters. Jerry Stackhouse had 19 points for Dallas.
