Blake Griffin could be back in the Los Angeles Clippers' lineup before the end of December.
Griffin has ramped up his rehab from a sprained medial collateral ligament injury to his left knee.
Griffin was initially expected to miss up to eight weeks when he suffered the injury on Nov. 27.
Griffin went through a variety of drills Tuesday with Clippers assistant coach Sam Cassell and Larry Abney, the team’s basketball operations assistant.
