What happened: Igor Cavalcanti knocked out Oscar Ravello in 1:38, and Akbar Abdullaev finished Ednilson Santos in 19 seconds. Luis Hernandez submitted Hugo Guillon at 1:01 of the second round, while Tyshawn Williams beat Antonio Monteiro by decision to stay unbeaten.

Why it matters: Contender Series cards turn on decisive performances, and Week 6 delivered four finishes in five fights. Abdullaev, Hernandez and Williams all preserved unbeaten records, giving the night multiple prospects with momentum beyond the main event.

What to watch: The next development is how quickly the standout winners are moved into bigger opportunities. Abdullaev's 19-second stoppage and Perea's main-event finish are the results most likely to carry forward.
