It looks like UFC Fight Night 28 will feature at least 12 bouts, as the September 4th card has reportedly booked Kenny Robertson vs. Joao Zeferino and Francisco Trinaldo vs. Piotr Hallman. The UFC on FOX Sports 1 card will be hosted by the Estadio Jornalista Felipe Drumond in Belo Horizonte, Brazil.

Word of the Robertson-Zeferino bout was reported by, however, since then the UFC Brazil Twitter account has confirmed the match-up. Robertson (12-3) could be facing the chopping block if he loses to Zeferino, as the experienced wrestler lost a tightly contested, majority decision to Sean Pierson at UFC 161, which dropped his Octagon record to 1-3. Prior to facing Pierson, Robertson tapped out Brock Jardine with a nasty looking, modified knee bar at UFC 157 in February.
