Which kind of headbutt was Bairstow's?
England say there was no headbutt, Australia say there was. So we have put our heads together to investigate the world of the sporting headbutt
This occurs when two sportsmen are standing in close proximity, often amid a melee of other players, and one makes a slight, surreptitious neck movement towards the other to make contact with his head. There's no movement of the legs or back in this kind of butt, which makes it harder to detect. Also, it's sometimes tough to tell whether a player has meant to butt the other or just square up, brow to brow, and say hello. In the incident depicted above, for example, Marouane Fellaini, the Manchester United midfielder, appeared to just slowly lower his head onto that of Sergio Aguero, the Manchester City forward. Whether or not a standing butt is considered a butt at all really depends on the speed and intensity of the neck movement. But it can be confusing. Fellaini was sent off for his slow nod, but when Luis Figo, the Portuguese footballer, made a sharp snapping motion with his neck to deliver a standing headbutt to Netherlands midfielder Mark van Bommel in a 2006 World Cup game, he was given just a yellow card.
This is the kind of thing you'll often see when two mates are simply joshing around, as Bairstow says he was doing with Bancroft. One person places his head on the other's and then pushes forward, making it more of a head push than a headbutt. This rarely causes any sort of injury or harm, but can be used as a means of intimidation. Joe Hart, the England goalkeeper, received a yellow card for a head push on footballer George Boyd in a Premier League match. As you can see from the depiction above, Hart starts with his head already touching Boyd's and then stretches his neck forward.
Some headbutt aficionados on social media have pointed out that Bairstow is shorter than Bancroft and would have had trouble executing a butt. Well, perhaps he employed the uppercut technique, as American boxer Victor Ortiz did in his bout against Floyd Mayweather Junior. As seen in the depiction above, this butt is delivered by a shorter man crouching down and then springing upwards to smash his head into a taller man's jaw or forehead. Argentinian footballer Ariel Ortega used a variation of this butt against Netherlands goalkeeper Edwin van der Saar, who is almost a foot taller than him, in the 1998 World Cup quarter-final. Ortega was sat on the ground, and when van der Saar bent down to harangue him about diving, Ortega sprang up and smashed his head into the big man's jaw.
