209 or 187? After Nate Diaz criticizes, Kamaru Usman fires back

If he fights the 209’s most prominent representative inside the cage, UFC welterweight champion Kamaru Usman thinks he’ll have a “187” on his hands.

That’s what Usman (19-1 MMA, 14-0 UFC) told Nate Diaz on Tuesday.

“187” is seemingly a reference to an often-used police code for murder.

The spat between the two welterweight fighters transpired on Twitter and began when Diaz (20-13 MMA, 18-12 UFC) issued a tweet that criticized Usman for his upcoming rematch against Colby Covington, a fighter who the 170-pound titleholder already defeated once.
