NFL and UFC mourn Arthur Jones, brother of Jon Jones, at 39

When Arthur Jones, former NFL defensive end, died at 39 on October 3, 2025, the sports world stopped in its tracks.

The sudden loss reverberated from Baltimore to Las Vegas, catching fans of both football and mixed‑martial arts off guard. Arthur was the eldest sibling of two of the most dominant athletes of their generations: his middle brother Chandler Jones, a four‑time Pro Bowl defensive end, and his youngest brother Jon Jones, former UFC light heavyweight and heavyweight champion.

Arthur’s own résumé reads like a highlight reel. Drafted by the Baltimore Ravens in 2010, he helped the franchise clinch Super Bowl XLVII, recording a sack and a fumble recovery in the 2013 championship game against the San Francisco 49ers. After stints with the Washington Redskins and Indianapolis Colts, he hung up his cleats at the end of the 2017 season.

Remembering a Champion’s Brother

Ravens General Manager Eric DeCosta, who also served as the team’s director of player personnel, released a heartfelt statement: “We are terribly saddened to learn of Arthur Jones’ sudden passing. His big, bright smile, infectious energy and eternal positivity created a presence that continuously uplifted others.”

DeCosta’s words echo a sentiment that circulated across social media feeds: Arthur wasn’t just a great player; he was a beacon for everyone around him. Fans recalled seeing his beaming grin at Ravens’ charity events, while teammates whispered about his locker‑room jokes that could defuse the tensest moments of a close game.

UFC’s Unified Tribute

The Ultimate Fighting Championship issued a concise but sincere note: “UFC is saddened to hear about the passing of Arthur Jones. Our thoughts go out to his family, friends, and loved ones.” The brevity of the statement belied the depth of feeling in the MMA community.

Within minutes, marquee names were posting tributes. Conor McGregor typed on X (formerly Twitter): “Very sad to hear this news. Arthur was a great man, a friendly giant. God speed Arthur Jones.” McGregor’s post drew hundreds of retweets, underscoring how Arthur’s reputation crossed sport boundaries.

Former UFC fighters joined the chorus. Josh Thomson wrote, “Truly sad to see someone's life gone so soon. Our sincere condolences to you Jon Jones and the entire Jones family.” Clay Guida posted an Instagram photo of Arthur with the caption, “God Bless Big Bro,” while Derek Brunson summed it up in three words: “A good dude.”

The Jones Family Legacy

Arthur was more than a sibling; he was the glue that held the Jones brothers together. He never missed Jon’s UFC title fights, and, as Jon later revealed in a 2024 interview, Arthur was the only man who’d seen all of his fights without ever watching a loss. “He was my rock,” Jon said, his voice cracking. “If you’re in a cage and you hear a roar from the crowd, it’s probably Arthur cheering for me.”

Chandler, who has earned 79 sacks in his NFL career, recalls family dinners that felt like training camps. “We’d argue about who had the toughest opponent that week,” Chandler laughed, “but Arthur always made sure we ate together, no matter how busy we got.”

Impact on Two Worlds

The ripple effect of Arthur’s death is palpable in two distinct yet intertwined fan bases. For Ravens supporters, the loss feels personal—many grew up watching Arthur’s defensive plays and now mourn a hometown hero. In MMA circles, the tragedy hits a community that prides itself on brotherhood, a value Arthur embodied both on the field and in the stands.

Statistically, the NFL has seen fewer than ten deaths of former players under age 40 in the past decade, a stark reminder of the health challenges athletes can face long after retirement. Meanwhile, the UFC has lost only two former competitors under 45 in the same period, making Arthur’s passing a particularly rare cross‑sport occurrence.

What Comes Next?

Jon Jones, who announced his retirement from mixed martial arts earlier this year, has hinted he might step into a mentorship role for younger fighters, perhaps channeling the support Arthur offered him. “If there’s one thing Arthur taught me, it’s to stay humble and keep lifting others up,” Jon said in a recent press conference.

The Ravens organization plans a moment of silence before their next home game against the Pittsburgh Steelers, and a tribute video will air during the halftime show. The UFC, meanwhile, is considering a special segment on its upcoming “White House” card in 2026 to honor athletes who have made a lasting impact beyond the cage.
