Daniel Cormier has been at the top of UFC's food chain since 2013, but that could have come to a violent end.
The now-former heavyweight champion suffered a knockout loss at the hands of Stipe Miococ at UFC 241 this past weekend, just the second official loss of his career.
Stipe Miocic is now a two-time UFC heavyweight champion, while Cormier, 41 may have fought for the very last time.
Cormier, one of just three men to have held both the UFC heavyweight and light heavyweight championships, is likely headed to retirement - his dreams of a third fight with Jon Jones now dead in the water.
The Fight Club breaks down the UFC 241 main event, looking at the repercussions for both the heavyweight division and Cormier's fighting career.
The event in California last Sunday also had two key matchups at welterweight and middleweight, including the victorious return of Nate Diaz.
All that, plus Conor McGregor's latest public brain fade has come to light.
