Conor McGregor may be the underdog going into his August 26th fight against Floyd Maywaether, but the Irishman continues to dominate the battle of mind games leading up to the bout.

The latest chapter in the ongoing saga of insults actually started with an Instagram post from Draymond Green. The Golden State Warrior thought he had found a picture of McGregor wearing his jersey, and took to the Gram to inform McGregor that he was backing Mayweather in the fight. "We rocking with Floyd bro not you...," Green said in the caption. "take that off bruh @thenotoriousmma."

McGregor was quick to respond, correcting Green on whose jersey he was actually wearing by commenting below the photo, "That's C.J. Watson mate. I don't know who the f--- you are. No disrespect tho kid, keep hustling and stay in school."

McGregor continued with another comment, saying, "Now ask yourself why I'm rocking C.J. when I don't know or give a f--- about basketball. I dribble heads off the floor. Not a ball. This is no game here kid."

While the Watson jersey might seem like a peculiar choice, it does have significance in the build up to the Mayweather-McGregor bout in August.

Mayweather served 90 days in prison after seven alleged instances of assault against five different women. One of those women was Mayweather's longtime partner Josie Harris, who described C.J. Watson as her "summer love," according to a 2014 story in USA Today. Harris said that one night she awoke to Mayweather screaming and grabbing her hair after he had read texts exchanged between herself and Watson.

McGregor has brought up Watson in the lead-up to his fight with Mayweather before, although the subtle reference came long before the fight was officially announced. This tweet from back in January shows that McGregor must have had this fight at the forefront of his mind for some time.

Until McGregor and Mayweather finally come to blows on August 26th, their war of words is only going to escalate.
