Pierce, Garnett lead Celtics over Magic 97-84

Boston lost All-Star point guard Rajon Rondo at the beginning of the week to a torn knee ligament and learned Friday that promising rookie Jared Sullinger is also out for the season following back surgery.

"With the injuries, a number of guys are stepping up and that's what we are going to need," said Pierce, who had 14 points, 11 rebounds and seven assists despite sitting out the fourth quarter.

Garnett finished with 14 points and 10 rebounds, Jeff Green scored 17 and Courtney Lee had 14 points and five assists for the Celtics.

"The production is coming from everybody," said Lee, who inherited Rondo's job at point guard. "Rondo, he's our playmaker. He's racked up a lot of assists with his playmaking ability. And now we just have to move the ball and make sure we are in the right spots to execute the offense."

The Celtics had assists on 30 of their 42 field goals while shooting exactly 50 percent. Jason Terry and Leandro Barbosa scored 12 each for the Celtics, who had six players in double figures.

"We have to be a team by committee," coach Doc Rivers said. "I'm asking guys to play different spots. It does create confusion on the other end."

It helped that the Celtics were facing Orlando, which last won on Jan. 16 and has been dealing with injury problems that rival those of the Celtics. The Magic were without their top two scorers in Aaron Afflalo (calf) and Glen Davis (broken left foot), then lost point guard Jameer Nelson to a bruised left forearm.

"It's part of basketball and we'll continue to deal with it," coach Jacque Vaughn said. "It means other guys have to fill in and fill roles and we'll keep at it."
