Former WWE Tag Team Champion Sir Mo Dies at 58: ‘A Kind, Humble, Deeply Devoted Man’

Former professional wrestler Bobby Horne, who entertained fans for decades as Sir Mo, has died after battling several health issues in recent years.

He was 58.

Book Pro Wrestlers announced Horne’s death on social media late Sunday night.

“It is with great sadness that we share the news that Bobby Horne, known to wrestling fans around the world as Sir Mo of Men on a Mission, has passed away,” the pro wrestling booking company wrote, adding that “Bobby…made his mark in the wrestling world with his infectious energy, booming personality, and unmistakable charisma.”

The booking agency wrote that Horne used a “blend of positivity, showmanship, and unity” to bring “a fresh burst of life to WWF programming” in the early 1990s.

Horne first entered the ring in 1991 and later wrestled for WWE from 1993 until 1996, briefly winning the promotion’s tag team championship in March 1994 alongside the wrestler Mabel. The North Carolina native spent the rest of his career on professional wrestling’s independent circuit, mostly as a tag team wrestler. He won several tag team championships throughout the United States and was later elected into both the New England Pro Wrestling Hall of Fame as well as the Memphis Wrestling Hall of Fame.

In his later years, Horne battled a number of health issues and often shared updates about his health on social media from his hospital bed. 

“My colon hasn’t worked in three years,” the wrestler said in a video update from a hospital bed in late July, shortly after announcing he had “major intestinal surgery.”

Earlier this month, a fundraiser set up to help Horne and his wife Denise Jones pay for his medical bills said he was in the ICU after contracting “a severe blood infection and pneumonia.” He previously had a kidney transplant in 2018 and “endured a serious case of COVID-19” in 2022 that landed him in the ICU shortly before needing a hernia surgery. 

Pro wrestler Ryzin, who worked with Horne in recent years at SOAR Wrestling Worldwide in Dallas, wrote on social media earlier this month that the former WWE star was “fighting for his life” amid his latest health issues.

“As the years went on, Bobby continued to contribute to wrestling both in and out of the ring — training others, helping at events, and always giving back to the business he loved,” the memorial for Horne read, adding that “beyond the bright outfits and booming entrances, those who knew Bobby personally describe him as a kind, humble, and deeply devoted man — someone who loved his peers, appreciated his fans, and never took a moment of it for granted.”

Several pro wrestlers paid tribute to Horne online Monday morning.

“Rest in peace Sir Mo!” wrote former WWE World Heavyweight Champion Mark Henry.

“Bobby was always good to me, keeping in touch with little messages over the years,” wrote WWE’s Adam Pearce. “Godspeed, Mo. I appreciate you and the time we shared. My heart goes out to his family, friends, and all affected.”
