on my forearm i got a big oval shaped one, its mostly gone away by now(as in blending in), but there was one time on turn where i did a flying slide save when someone shot the ball, and i ended up having all my weight basically on that arm as i slid sideways, so when i got up that spot had a good centimeter thick of burned frickin skin , i ended up using my undershirt to tie it off as it was bleeding all over.
(that was all on the old type of turf btw, that shit killed)
another time i was riding my bike with friends, and we were doing all kinds of offroad fun stuff, and i did a slight jump onto this roofing that was leveled ish a bit with the hill i was on, and i jumped off that with the bike, ended up hitting a puddle after landing and my bike skidded sideways with me stuck on it so my knee was fucked up beyond belief (the cement,concete,whatever it was, was not flat, it was pokey and sharp as fuck on a small scale) from being dragged on that shit, i remember i basically peeled the scab off a good 10 times before it healed nearly all the way, even then the skin has a line going down it by my knee now.
