Jontay Porter, a 6-foot-11 sophomore for the Missouri Tigers, re-tore the ACL in his right knee while rehabbing the injury in Denver, the school confirmed on Saturday evening.
Porter missed the 2018-19 season after tearing the ACL and the MCL in the same knee. He averaged 9.9 points and 6.8 boards as a freshman before declaring for the 2018 NBA Draft. He went through the draft process, but opted to return to school for his sophomore season.
He suffered the first injury in October.
Jontay is the younger brother of Michael Porter Jr., who missed almost all of his freshman season at Missouri with back problems.
