CM Punk and current UFC welterweight fighter Cathal Pendred got into a Twitter fight on Tuesday afternoon.

Punk claimed that Pendred was a boring fighter while Pendred was calling out Punk for being a former pro wrestler and the fact that he’s never been in an MMA fight before.

Check out the epic exchange down below:

Pendred (17-3-1) was on a nine fight winning streak prior to his last fight with John Howard at UFC 189, which he lost by split decision. Now, Pendred fights Tom Breese at UFC Fight Night 77 in Dublin.

Punk has yet to fight in the UFC and for one year now we’ve heard that he’s training and that he might be ready in early 2016.

There’s still no word as to who Punk will fight in his UFC debut.
