I've only been injured once, and that was about 15 years ago.
A boar done a job on the side of my kneecap, but it was my fault for not paying attention.
I was pulling a young dog off the boars back leg, with the intention of teaching it how to clean hold, but the boar spun around and opened my leg up to the bone. Nothing a few stitches didn't fix up, but could have been worse if it had connected with an artery.
Bumps and bruises are common, but not worth a mention.
