It was announced earlier yesterday prior to UFC 179, that Conor McGregor vs. Dennis Siver would headline a UFC Fight Night card in Boston in January.

McGregor spoke to media members in a pre-fight media scrum about the bout, and Dennis Siver’s past that includes a failed drug test.

“I’m going to go in there and I’m going to rip his head off. I’m going to punish him for it.”

“Every fighter poses a threat. I will not overlook any man. He has cheated in the past, that’s another thing I will use to get in and put him out a bit more. He was caught with the stuff that hides it. That’s how deep he was in that. How deep was he in that game that he was actually using stuff to hide it from the testing. That, to me, I don’t respect that in a bit.”
