Tony Wroten decided that having surgery is his best option.

The 76ers reserve point guard just doesn't know when and where he'll have the procedure to repair a partially torn anterior cruciate ligament in his right knee.

"I can't play with a partial tear to the ACL with the way I play, so it's best to get the surgery," Wroten said Wednesday before the Sixers played Detroit at the Wells Fargo Center.

The third-year veteran said he didn't know how long he would be sidelined. He leads the Sixers in scoring at 16.9 points per game.

Wroten was noticeably disappointed as he told reporters the news.

"I mean, who wants to have surgery?" he said. "Nobody wants to have surgery. . . . But it is what it is."

Wroten's season was derailed when he exited the game against the Atlanta Hawks on Jan. 13. Originally, the Sixers announced that the 6-foot-6, 205-pounder had sprained his right knee for the third time this season. The injury, however, was diagnosed as a partially torn ACL by a specialist last week in Los Angeles.

Wroten also suffered a torn ACL in his right knee in a football game as a high school junior in Seattle in 2009.

Wroten missed six games after spraining his knee against the Brooklyn Nets on Nov. 26. He was a late scratch against the Miami Heat on Dec. 23 because of another knee sprain.

MCW, Noel picked

Michael Carter-Williams and Nerlens Noel were selected to the play in the Rising Stars Challenge at the NBA all-star weekend.

The game, which will be played Feb. 13 at the Barclays Center in Brooklyn, has been modified. The league's top American rookies and second-year players will face the league's top first- and second-year players from around the world. The two Sixers will play for the American team.

Carter-Williams, a second-year point guard, was last season's rookie of the year. He took averages of 15.3 points, 7.1 assists, and 6 rebounds into the game against the Pistons.

Noel was averaging 8 points, 1.6 blocked shots, and 1.5 steals. He also leads NBA rookies in rebounds with 7.3 per game.

"Obviously, it was a goal of ours to be able to play in it at the same time with him just being a year ahead of me," Noel said. "It's a great opportunity for us. We are going to go in and represent the city of Philadelphia."
