Khabib Nurmagomedov has cast doubt over his UFC future after defeating Conor McGregor.

The Russian was involved in a worrying brawl after the match, which sees him awaiting an investigation from the Nevada State Athletic Commission and members of his team facing bans.

The biggest point of content from Nurmagomedov has been the treatment of his friend Zubaira Tukhugov, who could be banned for a scuffle with McGregor in the octagon.

As a result, Nurmagomedov took to social media and issued the following message: "If you decide to fire him, you should know that you’ll lose me too.

"We never give up on our brothers in Russia and I will go to the end for my Brother. If you still decide to fire him, don’t forget to send me my broken contract, otherwise I'll break it myself."

Khabib-Bellator speculation

In summary, Nurmagomedov has threatened to quit the UFC and his statement has led to a number of offers from elsewhere just days afterwards.

One such approach came from the WWE, but perhaps the biggest suggestion has come from 50 Cent who has been courting 'The Eagle' on Instagram to join Bellator.

It's even gone as far as Curtis Jackson claiming he will fly out to Dagestan to thrash out a deal and Nurmagomedov has sent positive replies on Instagram.

50 Cent's phone conversation

However, just how realistic is Nurmagomedov swapping the UFC for Bellator?

Well, Bellator chief Scott Coker has gone a long way towards answering that question by revealing his phone conversation with 50 Cent regarding the approach.

At the Bellator 208 event, he stated: “He called me yesterday and he said, ‘Hey, what’s going on with this?’

“I said, ‘Well, the commission’s involved. There’s a lot of steps to that whole situation.’

“I’d like to just – I told him, ‘Hey, let’s just stay clear of it because that has nothing to do with Bellator, it has to do with the commission and the fighter and the league.’ So that’s their business.”

In other words, hold your horses 50 Cent.

Despite all his talk on Instagram in recent days, it will remain mere speculation until the NSAC decide their punishment for Nurmagomodov and the UFC devise a plan.

Of course, a crucial factor will regard the handling of Tukhugov which could make or break Nurmagomedov's loyalty to his current employers.

If the NSAC give a lenient punishment and White goes through on his plan to sack Tukhugov, then perhaps 50 Cent's phone conversations will become far more productive.

There's a still a long to go if Bellator are going to secure one of the biggest names in MMA and it would certainly be a blow for the UFC.

What it could mean for a McGregor rematch is another question, too.
