Daniel Cormier says he is considering his future in the sport after losing his heavyweight title in a shock defeat by Stipe Miocic at UFC 241.
Cormier said in an Instagram post he will “decide what I am gonna do now”.
“I can’t stress the disappointment and I am so sorry to all I have let down,” he added.
“This has been the most amazing journey. As soon as I decide you will all know right away.”
Cormier congratulated Miocic on a “tremendous victory” and apologised to his coaches and fans as well as his wife and children.
“I am so sorry you guys [his family] had to experience that,” he wrote.
“I never wanted y’all to see that and the hurt you guys showed breaks my heart every time I think about it.”
Miocic’s win saw him become only the fourth fighter in the sport’s history to recapture the undisputed UFC heavyweight title as he avenged his knockout loss to Cormier in July 2018.
The pair’s previous meeting saw Cormier beat Miocic in a first-round stoppage victory and end his opponent’s record-setting run as the most dominant world champion in UFC history.
