Philadelphia 76ers forward Arnett Moultrie is expected to be out until at least January with an injured left ankle that required surgery.
Moultrie suffered an injured medial malleolus of his ankle last week and underwent surgery on Thursday.
Moultrie appeared in 47 games last season, his first in the league, averaging 3.7 points and 3.1 rebounds per game.
The Sixers also announced on Friday that center Kwame Brown, who suffered a right hamstring strain during offseason workouts, will seek a second opinion.
Brown appeared in 22 games, starting 11 times, with the Sixers last season and averaged 1.9 points and 3.4 rebounds.
