The tension between UFC champion Daniel Cormier and WWE superstar Brock Lesnar came to a head at Madison Square Garden.

After beating heavyweight Derrick Lewis on Saturday, Cormier made history by becoming the first fighter in UFC history to defend two titles in different weight classes. Cormier's technical ground assault on Lewis did not make for an exciting bout, but Cormier made up for this during his post-match interview with Joe Rogan, where he called out former Lesnar.

"Brock Lesnar, when you come bring that brand new WWE title, too," Cormier said when asked about his potential foe and WWE Universal Champion. "I feel like being a WWE champion too. Let's go, Brock. Bring that belt if you want to come to my house."

Lesnar shoved Cormier in the ring during his post-win interview at UFC 226 back in July. The WWE champ's USADA-imposed suspension ends in January and it's assumed that Brock will not be defending his WWE title before then, so it seems like this clash will come to fruition.
