When Jon Jones retired from MMA in early 2025, he did so under somewhat complicated circumstances. By the time he hung up the gloves, he was irrefutably one of the greatest fighters in MMA history—maybe the best outright.

Former UFC champion Jon Jones shared an emotional tribute to his former NFL star brother Arthur, who died suddenly at age 39 in early October. On Thursday, Oct. 23, Jon shared a compilation video in memory of Arthur, who won a Super Bowl with the Baltimore Ravens in 2013, and penned a thoughtful caption.

It's been nearly three weeks since the tragic passing of former NFL defensive tackle and Super Bowl champion Arthur Jones. Jones comes from a family of well-known athletes, with his younger brother Jon "Bones" Jones being arguably the most famous of all.
