It’s fair to say that Colby “Chaos” Covington seems to have a massive beef with Ireland’s Cathal Pendred
Covington was unimpressed with Pendred’s contentious victory over Sean Spencer in Boston last weekend. Pendred was given the unanimous decision victory over Spencer at Fight Night 59, with the  judges scoring the bout 29-28, 30-27, 30-27 in favour of the Punisher.
The result of the fight worked the Covington into so much of a frenzy that he felt the need to call out the Dubliner on Twitter.
Let's see who is the tougher Irish American @PendredMMA no judges will be needed I promise @ufc @danawhite @FakeJoeSilva @SuckerPunchEnt

Lmao @PendredMMA saying "had no doubt I controlled the fight". You won't say that against me because I won't let it go to judges @ufc

The American welterweight then turned his attention to the entire SBG contingent in the UFC, calling into question their abilities as mixed martial artists, before having another pop at Pendred.
@Dunnie88x @AGBLKHPPY @ufc @TheNotoriousMMA @PendredMMA @PaddyHolohanMMA these guys are one dimensional. I am a complete fighter.

Why you favoriting all my posts @PendredMMA ? You acting like a girl. Respond like a man or stay scared and in hiding @ufc

Pendred finally broke his silence last night, responding to Covington’s trash-talking. The American then went to town on the Dubliner over the Boston fight again, implying that the former Cage Warriors champion is only in the UFC because of the popularity of Conor McGregor.
While Pendred decided to hold his tongue, “Chaos” tweeted an endless slew of insults directed at Pendred for a few hours.
@ColbyCovMMA You clearly don't know what you are talking about. Your stupidity is unbelievable! Fighting was obviously your ONLY option.

@PendredMMA Well, what are you in this business for??? To get horrendous gift decisions??? I'm here to fight! Not ride someone's coattail.

@PendredMMA @ufc Cathy you are barely talented enough to even step in the octagon. The judges had to bail out your pathetic career.

@baltim0re28 @GamebredFighter @PendredMMA @ufc Nope, the inbred is scared.

Not content with merely offending Pendred, Covington took aim at the entire country of Ireland and its diaspora. The tweet was deleted after causing a furore on social media but not before the Twitterati could get a screenshot.
Covington contested that his Irish heritage gave him carte blanche to send thee tasteless tweet.
@TheUFCDay It's funny these potato farmers can talk shit but can't take it back. I have Irish in my blood so them calling me racist is funny
