John Cena, Ric Flair and more stars paid tribute to the late wrestling legend Hulk Hogan after his death at age 71 on July 24. Ric Flair spoke with PEOPLE.

One week after Hulk Hogan died at his home in Florida, his cause of death has been revealed as acute myocardial infarction, commonly known as a heart attack.

Cena has squared off with several of his past foes with the roles reversed and him playing the bad guy. He defeated Cody Rhodes for the Undisputed WWE Championship at WrestleMania 41 and has since successfully defended it against Randy Orton at Backlash and CM Punk at Night of Champions.
