Los Angeles Clippers star forward Blake Griffin will undergo an operation on his right knee on Tuesday but is expected to return in January.
Griffin will have arthroscopic surgery to remove loose bodies from his knee and will be out for three to six weeks, the team announced.
Although Griffin played 38 minutes in Sunday's loss to the Wizards, four minutes above his season average (33.7) and three more than his career average (35.2), he has been bothered by soreness in his other knee, as well as his left calf.
Averaging 21.2 points, 8.9 rebounds and 4.6 assists, the 27-year-old has helped the Clippers to a 20-8 start.
In his absence, coach Doc Rivers will have to rely on forwards Marreese Speights, Wesley Johnson and Brandon Bass to play more integral roles in the Clippers' rotation.
