Celtics forward Gordon Heyward suffered a gruesome injury to his left leg tonight in the first quarter against the Cleveland Cavilers. In examining the replay, it appears Heyward went to the ground after sustaining both a fracture and dislocation to his left ankle. This typically involves a break to the distal end of the fibula and tears of the ligaments that stabilize the ankle joint to the foot and possibly the ligaments that connect the tibia and fibula. Treatment of this injury will involve surgery to stabilize the breaks in the distal fibula and medial tibia with plates and screws along with possible repair or stabilization of the torn ligaments. Recovery will depend on what surgery entails but typically it will be at least 6-8 weeks before Heyward is allowed to put weight on his left ankle and several months after to recover from the soft tissue injury. Estimates on return to play are likely to be 4-6 months. Expect Kyrie Irving to command an even larger presence in the Celtics offense while Jayson Tatum tries to step in to the rotation at small forward in Heyward’s absence.
