Many other penalties automatically become match penalties if injuries actually occur: under NHL rules, "butt-ending, goalies using blocking glove to the face of another player, head-butting, kicking, punching an unsuspecting player, spearing," and "tape on hands during altercation" must be called as a match penalty if injuries occur; under IIHF rules, "kneeing" and "checking to the head or neck area" must be called as a match penalty if injuries occur.
