Video appears to show headbutt hurt Gustafsson
The head-butt looks to land at the same time that Anthony Johnson is throwing a big overhand right at Alexander Gustafsson, but there’s no doubt the heads do collide.

At this past weekend’s UFC on FOX 14, Anthony Johnson stopped Alexander Gustafsson in the first round, but was it due to an illegal headbutt?
Some may dismiss the idea of a Johnson (19-4 MMA, 10-4 UFC) head-butt, accidental or not, as mere conspiracy theory. However, some videos, like the one above, have emerged that appear to show a clear foul dropping Gustafsson (16-3 MMA, 8-3 UFC) before an eventual first-round TKO loss in Saturday’s network-televised event in Stockholm.
The head-butt looks to land at the same time that Johnson is throwing a big overhand right, but there’s no doubt the heads do collide (check out the video below for an alternative angle).
