PORTLAND -- Portland Trail Blazers center Marcus Camby will undergo arthroscopic surgery later this week to repair a partial medial meniscus tear in his left knee, it was announced today by General Manager Rich Cho. "The MRI taken earlier today did not show anything significant," said Cho. "However, a more thorough review tonight from our team physician did reveal a partial tear." The exact date for Camby's arthroscopy has yet to be determined. A timeline for his return will be set following surgery. In 39 games (all starts) this season, Camby has averaged 5.9 points, 11.3 rebounds, 2.3 assists and 1.87 blocks in 28.7 minutes. He ranks fifth in the NBA in rebounds and 10th in blocked shots per game. Camby is the only player in the Western Conference averaging at least 11.0 rebounds and 1.50 blocks. He has grabbed at least 10 boards in 26 games and led the team in rebounding a team-high 28 times this season.
