Avery Bradley to have surgery

Celtics guard Avery Bradley will undergo right shoulder surgery and could miss the start of the season, Boston
director of player personnel Austin Ainge told reporters Sunday.

The surgery will take place Tuesday in Boston and will be the second shoulder operation for Bradley, who had season-ending surgery on his often-dislocated left shoulder in May and missed the remainder of the Celtics' postseason run.

The Celtics had to wait until Bradley had sufficiently healed from the left shoulder operation before proceeding with this anticipated right shoulder surgery.

But due to the wait, Bradley might not be ready for the start of the season. A source close to Bradley said Saturday that the third-year guard still could be ready for the start of camp, but the pessimism of the Celtics' front office suggests otherwise.

Asked about Bradley's return timeline, Celtics coach Doc Rivers told the Boston Herald: "It could be early in the season, it could be mid-December. We're just not sure."

With Ray Allen taking his talents to the Heat, the Celtics are left thin at shooting guard as they scramble to add depth to their roster, all without much to offer beyond the biannual exception.

Sources told ESPN.com's Marc Stein that the Celtics have serious interest in free-agent guard Courtney Lee, who met with Rivers on Saturday night.
