Philadelphia 76ers All-Star Ben Simmons underwent successful surgery on Monday to remove the loose body in his left knee, the Sixers announced in a press release.

Simmons will begin rehabilitation in Philadelphia immediately and will have a post-op evaluation in approximately two weeks.

Meanwhile, according to Adrian Wojnarowski of ESPN, the former No. 1 overall pick is expected to miss the rest of the 2019-20 restart due to the injury.

“Only a deep Sixers playoff run could keep a fleeting hope of his return alive this season, sources said. Even then, his return from the procedure — expected to take place outside of the Disney campus in the coming days — is largely expected to come next season. The Sixers are preparing now for a postseason run that will come without Ben Simmons, one of the league's most talented and versatile weapons.”

Simmons appeared in 57 games for the Sixers in 2019-20. He averaged 16.4 points, 7.8 rebounds and 8.0 assists in 35.4 minutes per contest while shooting 58.0 percent from the field and 62.1 percent from the free-throw line.

Could Simmons have played in his last game with the Sixers? It's possible since there have been rumors going around that Philadelphia general manager Elton Brand might split up Simmons and Joel Embiid this offseason.

JoJo and Ben are elite players in the NBA, but they don't mesh well with each other since Simmons doesn't have a solid perimeter game which leads to a lack of spacing in the post for Embiid to operate.
