Fights are typically scratched or altered when a single fighter is injured; it's a rare situation when two fighters scheduled to face each other suffer injuries at the same time.
But that's exactly what happened with UFC 168 opponents Shane Del Rosario and Guto Inocente. Both fighters were injured and have been removed from the event.
The UFC announced the news via its official @UFCNews Twitter account. It's unlikely that a replacement fight will be named.
UFC 168 takes place on Dec. 28 at the MGM Grand Garden Arena. It is headlined by a pair of title-fight rematches: Middleweight champion Chris Weidman takes on former champ Anderson Silva, while women's bantamweight champion Ronda Rousey takes on fellow The Ultimate Fighter coach Miesha Tate.
Other featured bouts include former UFC heavyweight champion Josh Barnett taking on Travis Browne, the hottest prospect in the heavyweight division. Jim Miller also faces Fabricio Camoes.
Del Rosario (8-2, 0-2 UFC) has suffered two consecutive losses to Stipe Miocic and Pat Barry since making his promotional debut at UFC 146 in 2012. Prior to the two losses, he had rung up an undefeated record since his MMA debut in 2006, mostly under the Strikeforce banner.
Inocente (6-2, 0-0 UFC) has yet to make his UFC debut after signing with the promotion when Strikeforce closed its doors. He fought one time in Strikeforce, winning a unanimous decision over Virgil Zwicker at Strikeforce: Barnett vs. Cormier in 2012.
Del Rosario trains with Team Oyama alongside flyweight Ian McCall, while Inocente is a member of the famed Blackzilians team in Florida.
