A chief second considering his boxer in danger of being seriously injured through continuation of the contest may throw a towel into the ring as a token of accepting defeat and immediately enter the ring, thus accepting responsibility for stopping the contest and causing his boxer to be disqualified. Only a chief second may take this action. Should any other second enter the ring during the round, he shall be ejected and the referee may order the contest continued. In case of a knock down, the chief second shall not throw the towel into the ring, nor enter the ring until his boxer has either regained his feet or been counted out.
