Pro wrestling legend Barry Windham is currently in intensive care after suffering a heart attack.

The 62-year-old Windham suffered a massive heart attack while traveling through the Atlanta airport on Friday night. He's now in the ICU after undergoing an emergency procedure.

"As a family, we are impatiently waiting to hear that he will be okay," Windham's niece Mika Rotunda wrote. "But as of now, the future is uncertain."

Mika Rotunda is the daughter of Windham's brother-in-law Mike Rotunda and is the sister of Bray Wyatt and Bo Dallas. She has started a GoFundMe campaign to help raise money for Windham's medical expenses.

Mika wrote that Windham doesn't have health insurance, and he's been limited with work due to the injuries he suffered during his in-ring career:

"With deep sadness I regret to inform that my uncle, WWE Hall of Famer, Barry Windham suffered a massive heart attack Friday evening. While traveling through the Atlanta airport, his darkest fear became a horrific reality as he went into cardiac arrest. He is currently in the ICU and has undergone an emergency procedure to save his life. As a family, we are impatiently waiting to hear that he will be okay. But as of now, the future is uncertain.

As is the future for many in his position. And for those who have formerly devoted their lives to their craft. Barry Windham, has an iconically, decorated resume as an American professional wrestler. He traveled all over the world for decades, entertaining people of all ages with his athleticism and undeniable charisma.

After those countless years of wrestling matches, traveling and entertaining world wide, he experienced a number of taxing injuries and ended up undergoing multiple surgeries. That led to other health complications. Barry hung his boots for the last time in the early 2000’s. Since then he has been limited with work due to his medical history as well as left without health insurance.

To face these times is one of great stress and hardship. As well as one that comes with extensive medical expenses he is taking on. That is overwhelming to say the least.

We are politely asking for any increment of financial assistance to help cover his medical expenses and bills and see him through this time."

Windham is best known in pro wrestling for being a member of the Four Horsemen. He held the NWA World Heavyweight Championship once in 1993.

Windham was selected as Rookie of the Year in the 1980 Wrestling Observer Newsletter awards. Windham also won Match of the Year in 1986 for a bout against Ric Flair from Championship Wrestling From Florida.

In 2012, Windham was inducted into the WWE Hall of Fame as part of the Four Horsemen alongside Flair, Arn Anderson, Tully Blanchard, and JJ Dillon.
