5 legendary boxers who have appeared in WWE

#4. Muhammad Ali appeared at the first-ever WWE WrestleMania event

Considered one of the greatest boxers of all time, Muhammad Ali stepped into the world of WWE during the first-ever broadcast of WrestleMania. Ali, in fact, had been involved in wrestling beforehand. In 1976, he appeared in the audience and then confronted Gorilla Monsoon in the ring following his match.

Ali had a big role to play at the inaugural WrestleMania event. He was named one of the special guest referees for the main event bout between Hulk Hogan & Mr T vs. Paul Orndorff & Roddy Piper.

Ali's last appearance in the world of professional wrestling came when he was involved in the infamous 1995 Collision In Korea event in North Korea.
