In 1927 the NYSAC (New York State Athletic Commission) finally saw fit to allow fighters to wear mouth guards during prize fights. The other issue under discussion was an attempt to standardize what constituted the "belt line" -- Allowing fighters to wear protective kidney guards was still four years away, the belief being, if a fighter wears a protective guard under his trunks it will encourage low blows; unsportsmanlike behavior. Better to leave the fighter unprotected than to impugn the game. [read sarcastically] At least fighters were now allowed to protect their teeth.
