Khabib Nurmagomedov has recently been crowned the UFC Lightweight Champion, following his win against Al Iaquinta at UFC 223.
The Russian defeated his opponent with a dominating performance, winning by a unanimous decision to take his MMA record to 26-0 and his UFC record to 10-0.
Nurmagomedov was heavily favoured to win the fight because his opponent barely had time to prepare for the bout.
The Eagle was originally supposed to face Tony Ferguson in a long-awaited match, but due to a knee injury, the interim titleholder had to pull out.
He was replaced by Max Holloway, but one day before UFC 223, he was pulled from the PPV and deemed unfit to fight due to extreme weight-cutting - as Iaquinta stepped in.
On literally 24 hours notice, the fact that the American actually lasted five rounds is very impressive, but he was never expected to win.
With that, Nurmagomedov now holds the belt that Conor McGregor was forced to vacate due to inactivity - and perhaps his behaviour in the build-up to April's event.
The Irishman appeared in New York with an entourage, went into a press event and then smashed a window of a bus carrying a number of fighters set to compete at UFC 223, injuring two people.
He was then arrested and will appear in court next month - and although being stripped of his title officially had nothing to do with that, he'll still be looking for more revenge on Khabib.
It's believed that McGregor crashed the event with the intention of confronting Nurmagomedov over previous threats made to the Irishman's friend Artem Lobov, but the pair didn't meet face to face.
Now, following the decision to make Khabib the undisputed lightweight champion, he's offered McGregor a chance to settle things inside the Octagon, firing a warning to The Notorious one.
“When you see him, tell him: Conor the game has changed, now you have to play like a grown up man," Nurmagomedov wrote on Instagram.
"There will no longer be locked buses with security inside and outside, now you have to solve these problems alone, and if you do not want it, just say so, everybody will understand.”
McGregor will have to wait for the outcome of his trial next month before any fight can be made between the pair.
Although, there has already been talk that the McGregor camp is interested in challenging Nurmagomedov, so fans will be hoping the former "Double Champ" will be stepping inside the Octagon again soon.
