"I'm told NY Giants coaches Joe Judge and Marc Colombo got into a fistfight this morning," McIntyre reported. "Punches thrown. I'm told Colombo got the better of him, and Judge fired him instantly."
The story is WILD ... considering Colombo is 6-foot-8 and played offensive tackle in the NFL for a decade.
But, when we reached out to the Giants for comment ... a rep told us straight-up, "There is absolutely no truth to that."
Giants reporter Ralph Vacchiano says the firing actually all stemmed from Colombo being unhappy with Judge's decision to bring in former Patriots offensive line guru Dave DeGuglielmo to help Colombo with the unit.
... Marc Colombo did not like that idea and voiced his displeasure. There was an argument, but nothing at all physical, several sources said. It was clear that a Colombo-DeGuglielmo pairing wasn't going to work, so Judge decided to fire Colombo instead.
