Two-time WWE Hall of Fame wrestler Ric Flair is resting after having surgery on Monday.

A representative for the showman known as "Nature Boy" says the 68-year-old wrestler was admitted to the hospital for routine monitoring. Melinda Morris Zanoni of Legacy Talent asked on Twitter Monday for "prayers & positive energy" because Flair has "tough medical issues."

The tweet also said the issue was not related to his heart.
