COLUMBIA, Mo. – Missouri freshman Michael Porter Jr. has been cleared for all basketball activities, a source confirmed to the Tribune on Thursday afternoon.

CBS Sports college basketball reporter Jon Rothstein first reported the news via Twitter, citing an anonymous source.

Missouri will have media availability at noon Friday. A team spokesperson said that coach Cuonzo Martin would address the media then.

Porter, who has played just two minutes this season because of Nov. 21 back surgery was expected to be in Dallas on Thursday for an appointment with his doctor.

That appointment, according to Martin, was when he expected to have an update on whether Porter would be cleared to return to practice.

Since playing two minutes against Iowa State in the Nov. 10 season opener, Porter has not seen the floor.

He had a microdiscectomy on two spinal discs, done by surgeon Andrew Dossett on Nov. 21 in Dallas and has been rehabbing since, he said.

Though Porter, the No. 1 player in the 2017 class, hasn’t played, he has been working with strength and conditioning coach Nicodemous Christopher in his rehab.

“We are jumping, running, all that stuff,” Porter said in an interview Feb. 9. “We are going really hard getting me ready.”

Missouri is 18-10 and in a six-way tie for third place in the Southeastern Conference and is a projected seven-seed in the NCAA Tournament.

Martin said Feb. 9 that Porter would need to practice before playing in a game.

“I think the first thing, once cleared, it’s to be healthy, because you still have to practice. It’s not like he went down two weeks ago, so that’s a long time of not getting up and down the court,” Martin said.
