MMA Fighter Isaac Johnson has died after reportedly being injured during a match near Chicago Friday night.
NBC 5 Chicago reports Johnson collapsed after suffering an injury during his fight against Mario Aleksandrovski at Cicero Stadium.
An ambulance was called to the stadium at 8:38 PM local time to transport “an injured fighter” to the hospital … and Johnson passed away a few hours later, just after midnight.
The Cook County Medical Examiner’s Office has scheduled an autopsy to determine Johnson’s cause of death.
Joe Goytia — promoter of the Matador Fighter Challenge, the event Johnson was taking part in — told Fox 5 Washington, D.C. that Johnson passed the mandatory physical before the bout.
