Frank Mir is back and better than ever.

After four consecutive losses, the two-time UFC heavyweight champion bounced back in a big way by knocking out Antonio Silva just 100 seconds into Sunday’s UFC Fight Night main event in Porto Alegre, Brazil.

Prior to Sunday, Mir hadn’t won since December 2011.

“This is me,” Mir said, via “I took time off, I rested. I’m facing top five guys four fights in a row, hindered and injured and not being 100 percent. But I have that never say die attitude where I would never turn down fights.”

Here are the results from the rest of Sunday’s bouts:

Michael Johnson defeats Edson Barboza (unanimous decision)
Sam Alvey defeats Cezar Ferrieira (knockout)
Adriano Martins defeats Rustam Khabilov (split decision)
Frankie Saenz defeats Irui Alcantara (unanimous decision)
Santiago Ponzinibbio defeats Sean Strickland (unanimous decision)
Marion Reneau defeats Jessica Andrade (submission)
Matt Dwyer defeats William Macario (knockout)
Mike de la Torre defeats Tiago Trator (TKO)
