WASHINGTON -- Antawn Jamison's ailing shoulder will keep him off the court well into the regular season.
The Washington Wizards announced an estimated recovery time for Jamison's injury Friday, saying he's likely to miss the first eight to 13 games.
The two-time All-Star forward partially dislocated his shoulder trying to block a shot in an exhibition game against Cleveland on Oct. 14. The Wizards originally ruled him out for the rest of the preseason until the injury could be re-evaluated this week.
Team president Ernie Grunfeld said doctors have had a chance to look at the shoulder again, and that Jamison is expected to be out three to five weeks.
The news is another blow for a franchise that has had three straight seasons marred by injuries to marquee players.
Jamison had a healthy year, missing only one game and leading the team in scoring at 22.2 points per game. He also averaged 8.9 rebounds.
Andray Blatche and offseason acquisitions Fabricio Oberto and Mike Miller will vie for more playing time during Jamison's absence.
The Wizards open the season in Dallas on Tuesday.
