The Commission's policy is that a referee's competency is accepted, but the referee shall, at all times, avail himself/herself of the trained and expert judgment of a physician's greater knowledge of a boxer's well-being; and he/she should, at all times, feel free to call upon the physician to counsel him/her as to the advisability of permitting a boxer to continue or terminate a contest because of physical circumstances. The ringside physician may examine a boxer at any time he/she feels it necessary and may direct the referee to halt a contest if in his/her opinion the boxer is unable to continue.
