O’Haire is best remembered for his time in WCW towards the end of the company’s existence. It was Scotty Riggs, another WCW alumnus, who broke the unfortunate news to the Twittersphere.
“Just got a message that former wrestler Sean O’Haire has passed away. #RIPSeanOHaire,” Riggs posted.
Tributes to O’Haire, real name Sean Haire, began to pour in from fans who best remembered the sizeable superstar as a breakout competitor. The WCW Power Plant product initially teamed with fellow grad Mark Jindrak and soon began challenging for the WCW Tag Team Championship. The duo were unsuccessful at first, but after helping form the Natural Born Thrillers, the duo captured the title, only to soon after split with O’Haire teaming with Chuck Palumbo and again holding the belts.
O’Haire’s contract was picked up by WWE amid the WCW purchase and he and Palumbo were kept together. Over their first weeks in WWE, the duo battled the likes of the APA and Brothers of Destruction over the WCW Tag Team Championship, eventually being written out of WWE storylines. O’Haire was sent to OVW and would sporadically appear on WWE Heat throughout 2002.
2003 appeared to be O’Haire’s breakout. As the year began, O’Haire was featured in vignettes as being a devil’s advocate. Once he debuted, however, the magic didn’t seem to be there. He was paired with Roddy Piper for much of this tenure, but slowly slipped off major broadcasts and parted ways with WWE mutually in 2004.
Following his WWE career, O’Haire worked in New Japan Pro Wrestling and independents in North America before retiring from wrestling in 2006. He then pursued a career in kickboxing and later MMA before retiring from the combat game.
