What happened: He struggled to reconcile the decision with a career that had produced only one loss. The 33-year-old signed with PFL three days after completing his UFC deal.
Why it matters: The move redirected a fighter nearing the UFC rankings toward a new bantamweight title path. Marcos can establish his place in that division with a successful debut.
By the numbers: Marcos is 18-1 with one no contest overall. He went 5-1 with one no contest across seven UFC bouts, closing the run with a second-round submission.
What to watch: His PFL debut will show how quickly he can enter the promotion's title picture.
