Jontay Porter has suffered another serious knee injury.
He tore his ACL during rehab in Denver with his brother, Michael Porter Jr., about a week ago.
Jontay Porter also tore that ACL during a scrimmage against Southern Illinois last October, days before the season was set to start for Mizzou.
Porter averaged 9.9 points and 6.8 rebounds per game in 2017-18 for the Tigers, and was named the SEC co-Sixth Man of the Year.
