Much like every other week in September thus far, the weekend ahead is a big one in the MMA world. Probably the biggest weekend in September so far! Invicta FC 19 takes place Friday night, with Irene Aldana, Tiffany Van Soest. Saturday is topped by UFC Fight Night: Brasilia, featuring Cris Cyborg and former bantamweight champion Renan Barao. Rizin Fighting Federation is Sunday’s big attraction with Kron Gracie and Hideo Tokoro headlining. It also includes MMA legend Mirko Cro Cop and the first round of their open-weight grand prix.
