UFC 263 has lost a scheduled lightweight matchup after one fighter was involved in a car accident. A preliminary bout between Matt Frevola and Frank Camacho will not proceed as planned after the unfortunate turn of events. Camacho (22-9 MMA, 2-5 UFC) was set to return to action after a year away from the cage but was involved in a car accident in Los Angeles, forcing him out of Saturday’s fight with Frevola (8-2-1 MMA, 2-2 UFC), a person with knowledge of the situation told MMA Junkie on Tuesday. Camacho’s injuries are not believed to be serious or life threatening
