Jones, the UFC’s reigning light heavyweight champion, meets underdog challenger Anthony Smith in the main event of UFC 235. After destroying Alexander Gustafsson in his return this past December, Jones heads into the weekend as the biggest betting favorite of his entire career. But despite the overwhelming odds, Smith is no easy out. “Lionheart” is a perfect 3-0 since moving up to the 205-pound division and carries with him one of the most unlikely backstories of any UFC title challenger in recent memory, having strung together a remarkable career turnaround after struggling for years on the regional scene.
