UFC 206 is need of a new main event.

Light heavyweight champion Daniel Cormier has been forced to withdraw from his Dec. 10 title fight against Anthony Johnson due to an injury, MMA Fighting has confirmed with multiple sources. The promotion is currently working on a new headliner, however, nothing is finalized just yet. The hope, as of right now, is to keep Johnson on the card.

This marks the second big fight UFC 206 lost this week: On Monday, Tim Kennedy revealed on The MMA Hour that he was in need of a new opponent after the Ontario Athletic Commission refused to license Rashad Evans. The UFC is hoping to book Kennedy vs. Kelvin Gastelum, but that fight is not official yet either.

UFC 206 is scheduled to take place at the Air Canada Centre in Toronto. The current co-main event is Anthony Pettis vs. Max Holloway. The rest of the main card features Donald Cerrone vs. Matt Brown and Cub Swanson vs. Doo Ho Choi.
