Trades in mixed martial arts - not something that dominates the headlines because, well, it's never really happened before.
ESPN's Ariel Helwani revealed earlier this week that there have been discussions that will see the UFC release former flyweight king Demetrious Johnson from his contract to send him to ONE Championship.
On the other side, the Asian promotion will reportedly let undefeated Ben Askren head to the UFC.
The reason behind the UFC's reported willingness to allow Mighty Mouse to leave the organisation is so that they can dissolve the 125-pound division, but the excitement is all about Funky heading to the UFC at long last.
Even though the moves haven't been confirmed, Askren has wasted no time in calling out some of the biggest names in UFC.
He's already been involved in a brilliant exchange with Darren Till, while the likes of Colby Covington and the Diaz brothers have also been on his radar.
Perhaps the biggest names he focused on, however, were Khabib Nurmagomedov and Georges St-Pierre.
Askren has long campaigned for a clash against GSP, while he was open to the idea of fighting The Eagle for the 165-pound title - one the UFC is yet to create.
From all of the names mentioned, Conor McGregor was the one name he didn't initially call out.
Although, that changed heading into the weekend as he finally called out the Notorious in his own unique way.
Heading over to his Twitter account, Askren claimed that the Irishman already has too much money, so he didn't need to sign up to get beat against him.
He tweeted: "Obviously I have [not] called out Conor McGregor yet, but you know he has way too much money to take one of the whippings I’m giving out,” Askren said in a Tweet directed at the Irishman.
“So why bother?”
Askren is currently unbeaten in 18 fights and it looks that he'll come out of 'retirement' to take on some of the biggest names the UFC has to offer.
One thing is for sure, neither man will take on an ordinary opponent inside of the Octagon next.
