As McGregor stated in his replies, the jersey is not Green's, but rather that of C.J. Watson, who played for the Warriors from 2007-2010 and has unpleasant ties to Mayweather.
Green, who now wears No. 23 for the Warriors, took to Instagram to criticize McGregor while posting a photo of him in a No. 23 Warriors jersey.
This will be very interesting to see if they keep exchanging insults, stay tuned and get your popcorn ready.
Green and McGregor are two of the best trash talkers in sports today. It wasn't Draymond Green's jersey.
He thought it was his jersey but then McGregor said that it was a C.J. Watson Warriors jersey.More news: New Game of Thrones trailer teases Daenerys and Jon's first meeting

Green followed with a weak response about how he's a bigger deal in the jersey number now.
This isn't the first time McGregor mentioned Watson to troll Floyd Mayweather. Watson was alleged to be texting Mayweather's ex-girlfriend in 2010 based on details that came from Mayweather's 2013 domestic violence case. She says he'd perused loving instant messages amongst her and National Basketball Association ball player C.J. Watson, portrayed in her book draft as her "late spring love".
[Josie] Harris [, the mother of Floyd's three kids, ] says she awoke with Mayweather screaming and grabbing her hair.
This is all too amusing.
McGregor is scheduled to fight the five-division world champion on August 26, in what is considered as one of the most anticipated boxing matches in history.
