UFC light-heavyweight champion Daniel Cormier has reportedly pulled out of his UFC 197 main event fight with Jon Jones on April 23 in Las Vegas due to injury.
The exact injury is unknown but it is thought to be a lower-body ailment as the 37-year-old was seen limping while attending a wrestling tournament in California last week.
The UFC have still to confirm everything and whether Jones will still be fighting on the card or not.
At UFC 182 last January, Jones defeated Cormier by unanimous decision in the main event.
Cormier (17-1) won the vacant title last May at UFC 187 when he submitted Anthony Johnson and in October at UFC 192 he beat Alexander Gustafsson in five rounds.
