UFC commentator Mike Goldberg today issued a public apology after lashing out at Twitter critics in the wake of his rocky debut as a play-by-play man for the NFL.

“I just want to apologize to everyone at FOX and elsewhere for my momentary lapse of reason Sunday night,” Goldberg wrote Tuesday afternoon on Twitter. “I let some mean-spirited folks on twitter get to me and I should have had thicker skin instead of reacting so quickly and emotionally.”

Goldberg dropped the F-bomb on one fan and called another a “douche” after receiving backlash from his call of Sunday’s Lions vs. Vikings game. On the broadcast, he misidentified players and coaches and on several occasions couldn’t accurately keep track of the action.

Earlier today, FOX announced Goldberg’s removal from Sunday’s broadcast of the Vikings vs. Bills game, slotting Tim Brando in his place opposite Brendon Ayanbadejo, who also drew criticism for his work alongside Goldberg this past Sunday.

“I don’t want to be a distraction on the upcoming broadcast Sunday, so we mutually agreed that it would be best to sit this next one out,” wrote Goldberg. “I’m not happy about it personally but, professionally, it’s the right thing to do after my mistake.

“Thank you to FOX and to others who have been so great to me and understanding.”

Goldberg has worked as a UFC commentator since 1997 and shares broadcast duties with color commentator Joe Rogan. Sunday’s NFL broadcast was his first as a football commentator, though he got his start on the mic as a play-by-play announcer for several hockey teams in his native Canada.
