From the Clippers’ release:
Los Angeles Clippers forward Craig Smith underwent a successful arthroscopic procedure today on his right knee. He is scheduled to be sidelined from four to six weeks.
Smith, who averaged 7.8 points, 3.8 rebounds and 16.4 minutes in 75 games played with Los Angeles last season, was re-signed by the Clippers as a free agent on July 20th.
If this timetable holds, Smith will be ready for the start of training camp.
