The Los Angeles Lakers may be without center Dwight Howard, who  remains a game time decision with a right shoulder injury, on Sunday when they travel to take on the Detroit Pistons at 1:00 pm ET.

The Lakers (21-26) improved to 15-4 when Bryant takes fewer than 20 shots and ended an eight-game road losing streak which dated back to Dec. 22. They're now 1/3 without Howard in the lineup after the All-Star center missed Friday's game to receive platelet-rich plasma treatments in his right shoulder.

Howard returned to Los Angeles for that procedure, but he's expected to rejoin the team in Auburn Hills -- the third stop on the Lakers' season-high seven-game trip.

If Howard can go, it's uncertain what D'Antoni will do with forward Pau Gasol, who has not been pleased with being relegated to the bench for the first time in his career. In Howard's place, and starting for the first time in seven games, Gasol finished with 22 points and 12 rebounds Friday.

Meanwhile, the Pistons (18-29) are hoping Gasol's fellow Spaniard will help them improve from 10th in the East.

Jose Calderon, acquired from Toronto on Wednesday in a three-team deal that sent long-time Piston Tayshaun Prince and Austin Daye to Memphis, could make his Detroit debut after missing Friday's 117-99 victory over Cleveland due to visa issues.

Coach Lawrence Frank said Calderon, averaging 11.1 points and 7.4 assists, will start at point guard when he's available, pushing Brandon Knight to shooting guard.

Detroit won 88-85 in the Lakers' last visit to Auburn Hills on March 6 even after Bryant's 19-foot fadeaway at the buzzer forced overtime.
