The UFC lightweight contender knocked out Poirier with a wicked combination at just 1:35 of the first round Saturday night in the main event of UFC Fight Night 94 in Hidalgo, Texas. With doctors tending to Poirier, who was still down, Johnson walked over, made a gesture with his arms and shouted "f*ck you!"
The two talked a lot of trash before this fight in the lead up and almost came to blows Friday at weigh-ins. Johnson feinted like he was coming toward Poirier after the staredown and then Poirier put a finger in his face.
Johnson, though, got the last laugh and elevated himself in the lightweight division with the big knockout.
