If there's anyone who could relate to what Ronda Rousey is going through, it's Mike Tyson.

The former heavyweight champion of the world ruled over boxing with an "Iron" fist, tallying a 37-0 record before being stunned and knocked out by James "Buster" Douglas in a February 1990 match that remains one of the biggest upsets in sports history.

Appearing on Conan with Conan O'Brien this week, Tyson said the first step for Rousey to recover from her brutal November knockout loss to Holly Holm is to reassess the sport she's in and realize that it's OK for a dominant fighter to lose.

"She has to understand... we're in the hurt business. And I don't care if you're the king of the hurt business. We're in the business where we get hurt," Tyson said towards the fallen former UFC bantamweight champ. "She just got to be seen. Come out the house, whatever. I seen she's been around. Show your face. You're human. She's just unfortunate that she's a Goliath."

This comes after last week's report that Rousey will be starring in a movie and needs more time to prepare for her rematch with Holm, postponing it past its originally scheduled July date.

Tyson added that defeating Rousey gave Holm her "life ticket, her meal ticket and that's a wonderful thing," as the other aspect of the fight game.

Tyson seems to think Rousey can come back, though.

When she gets back into the Octagon, will she avenge her loss against Holm?
