LOS ANGELES (AP) — Darren Collison scored 17 points, Brandan Wright added 14, and the Dallas Mavericks spoiled the Lakers debuts of Dwight Howard and Steve Nash, in a 99-91 opening-night victory in NBA action on Tuesday.

O.J. Mayo had 12 points as the revamped Mavericks pulled off a stunner in their opener, comfortably beating the starstudded Lakers without any help from injured Dirk Nowitzki.

Kobe Bryant scored 22 points while playing on an injured right foot, but the Lakers opened a season of enormous expectations with a dud of a performance.

Howard had 19 points and 10 rebounds while missing 11 of his 14 free throws before fouling out with 2:02 to play. Nash managed just seven points and four assists with seemingly little to do in the Lakers’ new offensive scheme.

Pau Gasol had 23 points and 13 rebounds for the Lakers.

Cavaliers 94, Wizards 84

CLEVELAND (AP) — Kyrie Irving scored 29 points, Anderson Varejao had a career-high 23 rebounds and Cleveland opened the season with a win over short-handed Washington.

Rookie Dion Waiters added 17 points for the Cavs, who led by 16 in the third quarter but needed big plays from Irving and Varejao in the final minutes to hold off the Wizards. Varejao had nine points and a career-high nine assists, two setting up dunks by Tristan Thompson in the last two minutes.

Jordan Crawford scored 11 points to lead the Wizards, who were without star point guard John Wall, power forward Nene and forward Kevin Seraphin. Wall, the former No. 1 overall pick, is expected to be out until late November with a knee injury.
