An unidentified player for the Racing Club Cubzaguais, a French rugby team, accidentally broke a teammate's nose with a head-butt (video below).
According to Sudouest.fr, the players were warming up for a game inside the locker room.
NZHerald.co.nz described it as a "motivational pre-match hype routine."
After the player was head-butted, he waited a moment and grabbed his nose.
The player who broke his teammate's nose led the bleeding man over to a bench as the mood in the locker room seemed to drop.
