Pau Gasol added 31 points and 14 rebounds in the Lakers' first game since losing Bynum, their starting center, for eight to 12 weeks with a torn medial collateral ligament in his right knee.
Bynum was hurt Saturday at Memphis. The center isn't expected to need surgery and said he was confident he would return in time for the playoffs.
