Davis injury sours LA's sixth straight win

Anthony Davis hits the floor hard during Los Angeles' big NBA win over New York on Tuesday night

A lower back injury to Anthony Davis has soured the Los Angeles Lakers' 117-87 victory over the New York Knicks that extended their NBA winning streak to six.

Davis bruised his sacrum - the bottom part of his spine above the tailbone - when he attempted to block a shot in the third quarter on Tuesday at the Staples Center.

He got knocked off balance and fell awkwardly, landing hard on his back before pounding the court in pain.

The six-time All-Star stayed down for roughly two minutes, but eventually rose with his teammates' help and slowly walked off unaided.

Davis didn't return to the game, however x-rays later proved negative. His agent, Rich Paul, said his client felt extremely sore.

The Lakers expect to have an update on Davis on Wednesday.

"We're just hoping and praying for the best right now," coach Frank Vogel told reporters.

"He's one of our pillars. He's our present. He's our future. He's one of the best players in the world, so he obviously means a lot."

LeBron James scored 31 points but the Lakers (30-7) didn't exactly celebrate becoming the second team to win 30 games this season.

Los Angeles hadn't won 30 games this quickly since the 2008-09 season, when Kobe Bryant's Lakers started 30-6 and eventually won the 15th of their 16 titles.

Davis, who will be an unrestricted free agent this summer, is the primary reason behind Los Angeles' swift rise to the top of the Western Conference.

He is averaging 27.7 points and 9.5 rebounds per game in his first season after the Lakers traded most of their young core to New Orleans for him.

The Knicks dropped to 0-3 on their four-game West Coast trip.

In other games, Australia's Matthew Dellavedova tallied a season-high nine assists in Cleveland's thrilling 115-113 loss to Detroit.

Derrick Rose hit the 15-footer with 27 seconds left to hand the Cavaliers their fifth straight defeat and fourth in a row at home.

In Toronto, Carmelo Anthony netted with four seconds left in Portland's 101-99 win over the Raptors.

Veteran Chris Paul scored 20 of his 28 points in the fourth quarter and overtime to lead Oklahoma City past the Nets in Brooklyn.

Sacramento came back from 21 points down in the third quarter to defeat Phoenix 114-103 and the Memphis Grizzlies beat the Minnesota Timberwolves 119-112.
