The Bulls said the rehabilitation from the Tuesday procedure in Philadelphia is six to eight weeks. They expect him to be ready for the start of training camp.
The 6-foot-10 Carter showed promise last season after being drafted with the No. 7 overall pick, averaging 10.3 points and seven rebounds in 44 games before a season-ending left thumb injury.
The Bulls missed the playoffs for the third time in four years and finished with one of the worst records in franchise history at 22-60.
