Rookie Ed Davis scored a career-high 17 points and pulled down 12 rebounds, Linas Kleiza and DeMar DeRozan added 16 points apiece, and the short-handed Toronto Raptors pulled off an 84-76 upset of the Dallas Mavericks on Tuesday night.

The Raptors were missing several key players, but took advantage of the injury absence of Dallas' top scorer, Dirk Nowitzki.

Toronto, which had dropped its past 10 games in Dallas and had lost nine of its previous 11 overall, got 12 points each from Amir Johnson and Leandro Barbosa.

Jason Terry scored 18 points and Caron Butler 15 for the Mavericks, who had won 17 of their previous 18.

Nowitzki had an MRI exam earlier on Tuesday that revealed a sprained right knee and the team said he was day to day. Nowitzki, seventh in the league with 24.1 points per game, was injured in the second quarter of Monday night's 103-93 victory at Oklahoma City.

Dallas led in the game's first minute, but trailed the rest of the way.

The Mavericks got as close as 71-68 with 7:41 left, but the Raptors answered with an 8-0 run capped by Davis' layup with 4:05 to play.
