Another season, another Blake Griffin injury.

The Los Angeles Clippers All-Star power forward will undergo “minor surgery” on his sore right knee, league sources told The Vertical’s Shams Charania, who added that Griffin is expected back in the lineup “at some point” in January.

Griffin missed a game earlier this month due to soreness in the same knee. The procedure was described to Charania as a “cleanup” by league sources.

The Orange County Register’s Dan Woike confirmed Charania’s report and clarified some details on both the procedure and Griffin’s timetable to return.

Griffin’s injury history is concerning both for the Clippers and for the five-time All-Star, who has the option to become a free agent after this season. As The Ringer’s Kevin O’Connor points out, Griffin always has had issues with his left leg. Adding an injury to his right leg presents a whole new set of potential issues.

Griffin is averaging 21.8 points, 8.8 rebounds and 4.7 assists per game this season.
