There is one part of the male anatomy that nobody wants disturbed on the football pitch, as Kohei Tazuka confirmed in extremely painful fashion.
The Kashiwa Reysol player was up against Lukas Podolski's Vissel Kobe side in the J-League when he tussled for possession with Hideo Tanaka.
And as he went down on the turf, Tazuka was left with a nice little reminder of the scuffle: a kick square in his family jewels.
Tanaka unsurprisingly received his marching orders while Tazuka was forced off on a stretcher - but not before the unfortunate player also picked up a yellow card for the original foul.
Judging by the video, we'd say he probably suffered enough already!
