Former Ultimate Fighting Championship heavyweight king Junior dos Santos steps inside the Octagon for the 18th time Saturday when he takes on surging contender Tai Tuivasa in the main event of the final UFC Fight Night Fox Sports card. Dos Santos is coming off a much-needed victory over Blagoy Ivanov earlier this year and with the state of the division, he could earn yet another title shot with a win over Tuivasa.
Since dos Santos won the title on the first UFC on Fox card ever, it only makes sense that he headlines the last Fight Night card before we start the ESPN era.
