LOS ANGELES: Los Angeles Lakers superstar Kobe Bryant has a broken bone in his left knee and is expected to miss six weeks, the NBA team said on Thursday. Bryant missed the first 19 games of the season as he continued to recover from surgery to repair a torn left Achilles tendon suffered in April. He had played just six games and averaged 13.8 points. Bryant was injured Tuesday in the third quarter of a 96-92 win over Memphis. He walked carefully to the bench but returned later to the contest and finished with 21 points.
