Despite not being Octagon-side to call the action, Joe Rogan remained an interested observer of Saturday night’s UFC Fight Night 36 card from Brazil.

The main event featured former UFC champion Lyoto Machida scoring a decision victory over ex-Strikeforce champ Gegard Mousasi. The win moves Machida closer to a future title shot, as he is now 2-0 at 185 pounds after dropping down.

Before the final horn sounded, “The Dragon” landed a handful of big-time head kicks to Mousasi, who took the brunt of the damage and never went down.

“Amazed at Mousasi’s chin (Saturday),” Rogan posted on Twitter. “Never seen a guy eat Lyoto’s head kick like that.”

Rogan was also impressed by Machida, who he said “is fast as a turbocharged (cheetah) at 185.”

The division is currently led by Chris Weidman, who defends his title later this year vs. Vitor Belfort. But with challengers like Machida and fellow UFC Fight Night winner Ronaldo “Jacare” Souza pouncing, it is getting deeper by the minute.

“185 is getting interesting,” Rogan posted. “‘Jacare’ is a real threat standing and on the ground. Even more impressive that he came into the fight injured (he mentioned an arm injury post-fight).”
