Williamson had his torn right lateral meniscus repaired on Monday. The club says his recovery will last six to eight weeks. The 6-foot-6, 285-pound former Duke star averaged 23.2 points in four preseason games. He missed New Orleans' final exhibition game in New York last Friday night.
The 19-year-old Williamson turned pro after one season in college, during which he averaged 22.6 points and was voted to the Atlantic Coast Conference's All-Defensive Team. He also averaged 8.9 rebounds, 2.1 steals and 1.8 blocked shots.
He was projected to start immediately at forward for New Orleans, alongside guards Lonzo Ball and Jrue Holiday, forward Brandon Ingram and center Derrick Favors. While it remains to be seen how coach Alvin Gentry will change his rotation in Williamson's absence, it appears 6-foot-9, 235-pound forward Nicolo Melli of Italy could be in line for more playing time.
Melli, who was acquired in the offseason, averaged 8.4 points and 5.4 rebounds this season.
