Former boxing champ Rocky Lockridge -- who later had the most famous appearance on the show "Intervention" -- has passed away at age 60, his family confirms.
Family members tell us Rocky died Thursday morning from complications from a stroke he suffered a while back.
Lockridge was a stud fighter back in the '80s -- racking up multiple titles with victories over guys like Roger Mayweather.
But, he later became addicted to crack cocaine ... and his family brought him on the A&E show, "Intervention," in an effort to get him cleaned up.
