What is turf burn?
Turf burn, or turf rash, is part abrasion and part burn:
"A related injury, "turf burn" . . . develops when an athlete, most commonly a football player, slides an exposed area of skin across artificial turf. Because artificial turf has a lower coefficient of friction than natural grass, especially when wet, the athlete slides a greater distance, thus generating heat and producing an injury that is part abrasion and part burn."
