Two more bouts have been added to the nearly complete UFC fight Night 28 (formerly UFC on Fox Sports 1 #3) fight card.
Welterweights Kenny Robertson will face Joao Zeferino while lightweight Francisco Trinaldo takes on UFC newcomer Piotr Hallmann on the Sept. 4 event.
Robertson (12-3 MMA, 1-3 UFC) lost his first two UFC bouts to Mike Pierce and Aaron Simpson before logging his lone UFC victory against Brock Jardine at UFC 157. He is coming off a loss in his last outing to Sean Pierson and is in desperate need of a win.
Zeferino (13-5 MMA, 0-1 UFC) will try to get his first UFC win when he faces Robertson. He made his promotional debut on May 18, losing a unanimous decision to Rafael Natal.
Trinaldo (13-2 MMA, 3-1 UFC) is on a two-fight winning streak with victories over C.J. Keith and Mike Rio. He also holds a UFC win over Delson Heleno.
Hallman (13-1 MMA, 0-0 UFC) will make his UFC debut against Trinaldo. He is riding an impressive nine-fight winning streak and hopes to extend it inside the Octagon.
