Video: Watch Conor McGregor run through Dustin Poirier at UFC 178

Dustin Poirier has been on a tear at lightweight, providing the kind of action-packed first round destructions that get MMA fans buzzing since moving back to 155 pounds.

Poirier’s impressive performances seem to make what Conor McGregor (17-2 MMA, 5-0 UFC) did to him at UFC 178 all the more amazing. When the two men met the action was all McGregor from the opening bell. At the 1:46 mark of Round 1 it was all over and McGregor was getting his hand raised.

McGregor will face Jose Aldo for the UFC featherweight title in the main event of UFC 189 on July 11.

Check out the video above to see what might be McGregor’s most impressive performance to date.
