Michael Porter Jr. underwent back surgery last week, a league source confirmed to BSN Denver.
It was the second time in the last nine months that Porter went under the knife. In November, the 6-foot-11 forward had a microdiscectomy of the L3 and L4 spinal discs while at the University of Missouri. The surgery caused Porter to miss all but three games of his lone college season and contributed to him falling to 14 in the NBA Draft.
Steve Aschburner of NBA.com first reported the news of Porter's most recent surgery.
