The Philadelphia 76ers say No. 1 overall pick Ben Simmons has had surgery to repair a broken bone in his right foot.
Team officials said Tuesday that Simmons went through the procedure in New York.
There is no timetable yet for his return.
Simmons fractured the fifth metatarsal bone during the 76ers' final training camp scrimmage last week.
The injury is the latest blow for a franchise that has had several injuries to lottery players, plus losing streaks of 26 and 28 games over the last three seasons.
Simmons, the 6-foot-10, 250-pound Australian forward out of LSU, was scheduled to start for the Sixers in their preseason opener Tuesday against Boston. Simmons was Philadelphia's first No. 1 overall pick since they drafted Allen Iverson in 1996.
Payne will not have surgery
Thunder guard Cameron Payne will be out for at least six weeks after fracturing a bone in his right foot during a scrimmage last week.
Payne had previously broken the fifth metatarsal and he had surgery in July. After consulting with specialists, he elected not to have surgery again, instead hoping the bone will heal on its own.
Thunder General Manager Sam Presti said Thursday that Payne will be re-evaluated in six to eight weeks, meaning he will miss the start of the regular season.
