It's seemingly all kicking off between Conor McGregor and UFC welterweight champion Tyron Woodley.
Earlier today, Woodley took a pop at McGregor for his half-hearted posturing with a chair during last night's UFC 205 press conference, as things got heated between 'The Notorious' and a furious Eddie Alvarez.
At today's weigh-in check, the pair crossed paths backstage, and a tense encounter was caught on camera by MMAFighting as a silent McGregor stared Woodley down before uttering, 'What's up'.

Taking to Twitter immediately after his bump-in with the lightweight challenger, Tyron Woodley gave his version of events to Ariel Helwani:
I said what's up then he tried to flex. Quickly he realized it was a NO FLEX ZONE💪🏼🚫Pretty much made him say what's up! JS

@arielhelwani Some of us are really about that that life! The quiet ones are the ones really from the slums. Don't make me go back.

Needless to say McGregor didn't remain silent on the matter for too long...

You can probably guess what McGregor's response was to being instructed never to call Woodley a 'bitch' again...

Depending on how both fighters get on at Madison Square Garden tomorrow night, we might yet see McGregor bid to become a three-weight world champion in due course.
