Daniel Cormier claimed UFC title No. 2 with a first-round knockout win over Stipe Miocic in the main event of UFC 226 from T-Mobile Arena in Las Vegas to capture the UFC heavyweight championship. 

The fight appeared to be headed toward greatness from the opening salvo. Cormier applied his patented pressure game to the heavyweight champion from the outset, fearlessly closing the distance with jabs, uppercuts and clinching while Miocic fired back counter punches. 

Then DC showcased the power that he has when fighting at heavyweight. 

Breaking away from another clinch, Cormier uncorked a massive overhand right that landed cleanly and put Miocic down to bring an early end to his night. MMA analyst Andreas Hale gave Cormier props for the finish:

Cormier is now the second man to hold two UFC titles concurrently, forcing his way into the conversation of the greatest mixed martial artists of all time:

An emotional Cormier described the feeling of winning his second championship:

After that, Cormier and Brock Lesnar had an in-ring confrontation, as Lance Pugmire of the Los Angeles Times detailed:

Cormier spent the first part of his MMA career in the heavyweight division, winning the Strikeforce Grand Prix and then starting off 2-0 when he first made the transition to the UFC. However, this was his first bout in the 265-pound division since 2013, when he defeated Roy Nelson via unanimous decision. 

Now Cormier sits atop the UFC's two biggest divisions with options as to where he's going to go next. 

Steven Muehlhausen of Sporting News reports that Cormier is keen to have a third fight with Jon Jones pending his year-long suspension and a heavyweight bout with Lesnar should the WWE talent be looking to get back into the fight game. 

Jeremy Botter of Bleacher Report reported that Lesnar is expected to be the next man up in the division with a targeted date in November:

However, those two huge fights have a deadline. DC intends to be done fighting when his 40th birthday comes around on March 20, 2019. 

"It’s a hard deadline," Cormier said, per Muehlhausen. "I love it. I love that I can go make my family the focus. I've done fighting for almost nine years now. I started when I was about to turn 31. I’m like, 'I know I will be done by 40. I want to see what I can accomplish.' I’ve accomplished a ton."

Now that list of accomplishments includes ending the best run for a champion in the heavyweight division. 

Miocic had set the record with three consecutive title defenses in the organization's land of giants. Miocic's run will still go down as one of the best in the sport, but Cormier's greatness just happened to be better on Saturday night.
