Mizzou basketball’s chances at a special season were dealt a major blow on Tuesday. Star freshman Michael Porter Jr. is likely out for the season.

The school’s official basketball Twitter account revealed that Porter will undergo surgery on Tuesday and “likely” miss the remainder of the season. The procedure, which is a microdiscetomy of the L3-L4 spinal discs, will be conducted in Dallas, Texas.

The recovery time for said surgery is estimated at 3-4 months, which means Porter is likely to be out of action through the end of Missouri’s basketball season.

“Our top priority as a program is the well-being of our student-athletes,” Mizzou coach Cuonzo Martin said via official release. “So Michael beginning this process to be 100% 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.”
