Tonight at Allegiant Stadium is when the 56-year-old UFC president’s vision for the combat sport he grew up watching finally gets under way.

Dana White found more enjoyment in watching Canelo Alvarez than a UFC title fight that was right in front of him. On Saturday night, the UFC president completes his first real foray into boxing by promoting one of the biggest fights in recent years.

CEO Dana White had a heated exchange with a reporter on Thursday during a news conference in Las Vegas ahead of Saul 'Canelo' Alvarez's boxing bout with Terence Crawford in two days' time.

Eight years after Dana White's false start in boxing, Canelo vs. Crawford appears to represent the launch of a new era. The unresolved question? Whether TKO arrives as the sport’s savior, or as its conqueror.
