Anthony Davis played almost a lone hand for the Lakers (24-6), posting 32 points and 11 rebounds as he fought through a suspected knee problem sustained after an awkward fall in the third quarter.

Defending champions the Raptors, meanwhile, set a franchise record with their incredible 110-107 win against the Luka Doncic-less Mavericks.
Kyle Lowry led the way with 32 points and 10 assists as Toronto (21-8) overturned a 30-point third-quarter deficit to record their largest-ever comeback victory.
