The past and present of the Ultimate Fighting Championship’s middleweight division will come together to determine its future when Israel Adesanya puts his undisputed title on the line in a UFC 271 rematch with former champion Robert Whittaker on Saturday at the Toyota Center in Houston.

Adesanya dethroned Whittaker with a sensational second-round knockout two-plus years ago and emerged as one of the sport’s pound-for-pound greats. The City Kickboxing star last competed at UFC 263, where he retained his championship with a five-round unanimous decision over divisional upstart Marvin Vettori on June 12. Whittaker, meanwhile, enters the cage on the strength of three consecutive victories. “The Ultimate Fighter: The Smashes” winner last appeared on April 17, when he outpointed Kelvin Gastelum to a unanimous decision in their UFC on ESPN 22 headliner.
