October 3 now stands as one of the most painful days in the life of UFC legend Jon Jones. Just weeks ago, the former heavyweight champion lost his beloved brother—39-year-old former NFL defensive lineman Arthur Jones—leaving a void that even the fiercest fighter couldn’t prepare for. Bones’ bond with his brothers has always gone beyond blood. They weren’t just siblings; they were lifelong best friends who grew up pushing, guiding, and inspiring one another.

Jones often credits his brothers for helping transform a kid from upstate New York into one of the most dominant and mentally resilient athletes in combat sports history. According to early reports, Arthur contacted doctors after experiencing cardiac distress, but by the time first responders arrived, the Super Bowl champion had already stopped breathing. For days, Jon Jones and his family remained out of the public eye, mourning in silence as they came to terms with the heartbreaking loss of the eldest sibling. But two weeks after Arthur’s funeral, the UFC icon has finally broken his silence.

Arthur Jones’ ‘legacy inspires’ Jon Jones every day

A few hours ago, Jon Jones took to Instagram to share a heartfelt tribute to his late brother, Arthur Jones, posting a video compilation that captured moments from Arthur’s early life and cherished times with family. The post also featured some of Arthur’s most memorable quotes, showcasing the deep bond he shared with his brothers, all set to the song “Walk Around Heaven.” Jones opened his tribute with, “In Loving Memory of Arthur W. Jones III,” reflecting on the lasting impact of his brother’s life.

He went on, “Arthur was not just a Super Bowl champion but a father, spouse, son, brother, everyone’s best friend, a gentle giant whose kindness and generosity knew no bounds. He had a love for the outdoors, whether it was duck hunting, fishing, or riding four wheelers with his family, Arthur brought pure joy, warmth and laughter to every moment spent around him.”

The former UFC heavyweight champion continued by emphasizing Arthur’s remarkable selflessness, writing, “Arthur’s generosity extended far beyond his friends and family.” The UFC legend shared that his elder brother was always deeply “involved” in charitable work and dedicated to giving back to the community.”His legacy inspires me every day. Our dad, Arthur Jones Jr, me, Chandler, Arthur Jones IV, and the rest of the family are committed to moving forward, striving to be the best versions of ourselves, just as he would have wanted.”

Closing the tribute, Jon Jones added, “King Arthur will truly be missed, he’s gone way too soon, but his spirit will live on in our hearts forever. Rest easy, big bro, you deserve it, you did amazing.”

Arthur Jones’ cardiac arrest was later revealed to be the result of his “preexisting medical condition.” He leaves behind his wife and two children — a son, Arthur IV, and a daughter, Syler. Following in his father’s footsteps, Arthur’s son is now pursuing football under the guidance and mentorship of his uncles, Jon Jones and Chandler Jones.

Following the passing of his brother Arthur Jones, Jon has stepped into the role of the family’s elder, taking responsibility for guiding his brother’s family—just as Arthur once helped Jon unlock his potential, transforming him from a young boy into the beast he later became. In his brother’s absence, Jon is now mentoring the next generation, particularly his nephew, Arthur’s son.

On the day of Arthur Jones’ funeral, October 11, his nephew Arthur IV gave Jon a reason to smile. Jon shared a series of family photos on Instagram, including moments with his younger brother Chandler, capturing the family coming together to support Arthur IV. Jon revealed that his nephew and his team are already making waves at the school level. He wrote, “Congratulations to my nephew Arthur IV and the team! Wishing y’all the best as you chase that state championship! Stay focused, stay humble, and finish strong.”

Arthur IV’s emergence as a talented young athlete highlights the resilience of the next generation of the Jones family, ready to carry forward the family legacy and uphold the values instilled by their elders.
