After being hospitalized Saturday morning for what his representatives referred to as "routine monitoring," WWE Hall of Famer Ric Flair appears to be dealing with something more serious. 

Flair, 68, is out of surgery and resting, WWE confirmed with CBS Sports on Monday, after the legendary pro wrestler was placed in a medically induced coma earlier in the day. 

Monday's episode of WWE Raw featured an update on Flair's health from announcer Michael Cole, who said he was "not out of the woods" after surgery in Atlanta. No further details have been released regarding the procedure or his recovery, although Pro Wrestling Sheet reported Saturday that Flair's hospitalization was for heart-related issues.

Melinda Morris Zanoni, Flair's agent and the CEO of Legacy Talent and Entertainment, originally tweeted Saturday that Flair was hospitalized and there was "no reason to panic." But Zanoni tweeted out a public plea for prayers early Monday after a change in Flair's condition.

Referred to in WWE as 16-time world champion (although Flair admits the real number is as high as 22), the power of Flair's popularity and brand has only increased in recent years through social media and regular appearances with various collegiate and professional sports teams. 

Many of Flair's contemporaries in pro wrestling sent out their support via social media. 

Flair is the subject of an ESPN "30 for 30" documentary that is set to air in November. He was also scheduled to appear for WWE at promotional events this weekend in Brooklyn, New York, for SummerSlam. 

In Flair's 2004 autobiography "To Be The Man," he revealed the development of a condition called alcoholic cardiomyopathy brought on "through my many years of partying." Flair described it as "a weakening of heart muscles" that was discovered when his heart began to skip beats.

Flair's daughter, who goes by the ring name Charlotte Flair, is currently a popular WWE superstar and multi-time champion.
