Jedrzejczyk headbutts Kowalkiewicz during UFC 205 faceoff

During Thursday's press conference, Conor McGregor and Eddie Alvarez stole the show. But the post-presser faceoffs were all about Joanna Jedrzejczyk and Karolina Kowalkiewicz.

The two Polish fighters were nose-to-nose, and had to separated by UFC president Dana White after the strawweight champion attempted to headbutt her opponent.

Jedrzejczyk and Kowalkiewicz traded words in Polish after the incident, and it's highly unlikely anything pleasant was said.
