Hahaha this reminds me of my only head injury on the cricket field. Funnily enough I was fielding. I was on the Mid-Wicket boundary when the batsmen skied one straight out to me. The sun was shining straight in my eyes but I held my ground because I'm not exactly going to deliberately leave a catch. I put my hands up to catch it but I couldn't exactly see the ball so it landed straight on my forehead, but somehow as it bounced off I managed to trap it against my head and claim the catch. I was then taken from the field and started spewing up, apparently that can happen after a hard knock to the head.
The worst thing was I had my sunnies on my head instead of on my eyes. The ball demolished them anyway
