COLUMBIA, Mo. – After a week and a half of speculation swirling around Michael Porter Jr.'s injury, there is finally some clarity.

Porter, a Columbia native and the nation's top 2017 basketball prospect, is likely to miss the rest of the 2017-18 season, Missouri announced Tuesday. He was scheduled to have surgery on his back Tuesday in Dallas.

The procedure, a microdiscectomy of the L3 and L4 spinal discs, has a projected recovery time of three to four months, Missouri said in a release. No further information was available.

“I really appreciate the support of my family and the Mizzou men’s basketball program as I begin this process," Porter, a preseason co-SEC player of the year and preseason All-American, said in a release. "I’m thankful for all the kind words and messages I’ve received from fans. Those mean a lot to me. I cannot wait to be completely healthy and playing the game I love, once again.”

He is expected to make a complete recovery from his surgery. A microsdiscectomy is a surgery meant to remove herniated disc material that is pressing on a nerve root or spinal cord. The L3 and L4 spinal discs are positioned in the middle of the lumbar spine and play an important role in supporting a person's weight.

After years of growing up watching some of the great Missouri teams play in Mizzou Arena, Porter's season will likely come to an end after playing just 1 minute, 40 seconds in a Missouri uniform. His minutes are rounded up to two minutes in the team's box score.

Porter, who entered the season as the nation's top 2017 prospect according to Rivals.com, headlined a freshman class that was ranked fourth nationally. Fans got to see him for the first time Oct. 21 at Mizzou Madness, where he won the dunk contest and on the first play of the scrimmage recorded a steal and threw down a fastbreak dunk.

He played 23 minutes in the scrimmage against Kansas and played in the closed scrimmages against Wisconsin and Missouri State. Neither of those games was the real thing, though. They weren't regular-season games at a sold out Mizzou Arena.

His highly anticipated debut, in front of a sold-out crowd, ended with him on the bench for the final 38:20 of the season opener. He finished with two points and two rebounds against Iowa State after reporting a pain in his leg before the game to coach Cuonzo Martin.

Because he was already in the scorer's book, Porter started and has not seen the floor since.

He was not on the bench for the team's game against Wagner or Monday's game against Emporia State. He also did not travel with the team to last Thursday's game against Utah.

Missouri is 3-1 through the first two weeks of the season.

“Our top priority as a program is the well-being of our student-athletes, so Michael beginning this process to be 100 percent healthy is important to all of us. Our focus has been on Michael’s well-being, just like every other player in our locker room," Martin said in the release. "We will continue to work every day to build Mizzou basketball into a program to be proud of. We’re preparing now for a trip that is a tremendous opportunity. I’m excited to get after it in Orlando.”

Missouri will travel to Orlando, Fla., for the Advocare Invitational, which will begin Thursday. The Tigers open the tournament against Long Beach State at 10:30 a.m.

After playing just two minutes through four games, Missouri announced, on Tuesday, that freshman Michael Porter Jr.’s season is likely over.

The Columbia native, preseason co-SEC Player of the Year and preseason All-American is scheduled to have surgery Tuesday, in Dallas, Texas. The procedure, a microdiscetomy of the L3 and L4 spinal discs, has a projected recovery time of three to four months, Missouri said in a release. No further information was available.

“I really appreciate the support of my family and the Mizzou men’s basketball program as I begin this process,” Porter Jr. said in a release. “I’m thankful for all the kind words and messages I’ve received from fans. Those mean a lot to me. I cannot wait to be completely healthy and playing the game I love, once again.”

Porter Jr., who entered the season as the nation’s top 2017 prospect according to Rivals.com, headlined a freshman class that was ranked fourth nationally. He missed the last three games due to injury, after playing just the first two minutes in the season opener.

Before the season opener, against Iowa State, Porter Jr. told coach Cuonzo Martin that his leg wasn’t feeling right. Because Porter Jr. was already in the scorer’s book, and to avoid Missouri from getting a techincal foul, he started and scored two points, added two rebounds in two minutes.

He has not seen the floor since.

Missouri, largely without Porter Jr., is 3-1 after Monday’s win over Emporia State.

“Our top priority as a program is the well-being of our student-athletes, so Michael beginning this process to be 100 percent healthy is important to all of us. Our focus has been on Michael’s well-being, just like every other player in our locker room,” Martin said in the release. “We will continue to work every day to build Mizzou Basketball into a program to be proud of. We’re preparing now for a trip that is a tremendous opportunity. I’m excited to get after it in Orlando.”

Missouri will travel to Orlanda, Fla., for the Advocare Invitational, which will begin on Thursday. The Tigers will open the tournament against Long Beach State at 10:30 a.m.
