LAKE BUENA VISTA, Fla. – All-Star Ben Simmons will have surgery on his left knee, a big blow for the Philadelphia 76ers and their hopes of making a run in this season's playoffs.

The 76ers announced Saturday that Simmons will leave the NBA's season-restart bubble at Walt Disney World. There was no immediate time frame for his return, and it's likely that no firm timetable on his recovery will be set until after the surgery.

Simmons left Philadelphia's game against Washington on Wednesday midway through the third quarter because of injury, officially diagnosed as a subluxation of the left patella.

Tests since revealed a loose body inside the knee, which led to the decision for surgery.

Simmons is averaging 16.4 points, 8.0 assists and 7.8 rebounds this season, and his 35.4 minutes per game leads the 76ers.

The 76ers have clinched a playoff spot and cannot fall lower than sixth in the Eastern Conference, no matter what happens in the remaining the seeding games.
