Jon Jones, after a brief retirement from MMA, has announced a dramatic career shift. The former UFC champion and widely considered the greatest MMA fighter of all time, has taken on the role of Chief Performance Officer at Ketone IQ, a ketone ester drink company. Jones cited a desire for a lasting legacy beyond fighting and stated his belief in the product, even becoming a co-owner. He retired from UFC after a long and successful career, citing a lack of motivation for a potential fight with Tom Aspinall.
