I once charged down a clearance and got it in the nuts. I was completely fine to chase it 10 yards and get the cross in, then as I was watching where the cross went suddenly felt the pain coming on and did the same.
Ha. Remember my mate running up as the ball was bouncing towards him,he meant to sort of stoop to chest it down and then pick up speed bombing down the wing but it didnt bounce high enough and hit him just underneath his bollocks. It was like a scene from Platoon as he went down in slow motion.
