Mike Tyson has always bowed down to Muhammad Ali, acknowledging "The Greatest" at every opportunity available.

So, there's no way that Iron Mike was going to miss being a part of Ali's funeral procession Friday in Louisville, Kentucky. Ali died late last Friday at the age of 74.

ESPN is reporting that Tyson took a red-eye flight from Las Vegas to Louisville so that he could serve as a pallbearer alongside fellow former heavyweight champion Lennox Lewis and Will Smith, who famously portrayed "The Greatest" in the 2001 biopic, Ali.

During Iron Mike's height as the baddest man on the planet and well after, Tyson has always been in awe of Ali, bowing down to his friend and hero during a memorable 1989 appearance on The Arsenio Hall Show.

He also mimicked the 'Ali Shuffle' in front of the man himself just a few years back.

Tyson also destroyed Floyd Mayweather's notion of being "The Greatest," calling him "delusional" and a "very small, scared man" in defense of Ali just last year.

The hearse carrying Ali's body is currently being driven 19 miles through Louisville, passing landmarks in the icon's life, Muhammad Ali Center and Ali Boulevard, before Tyson will assume his role as pallbearer during the formal funeral procession this afternoon.
