LAS VEGAS – Rafael Ramos Estevam had no problem matching Joao Elias’ early intensity at Dana White’s Contender Series 56 . In a scrappy back-and-forth battle, Estevam (11-0)  finished Elias by TKO in the second round , wearing him out with some ground-and-pound. Elias threatened with a lot of aggressive submission attempts early, but Estevam said he never once felt in danger.
