NCAA 3-1 Head Coach
SECTION 1. A head coach is a person employed or appointed by an institution to be responsible for the team’s actions on the field (usually the head coach also is responsible for the team’s actions off the field) and to represent the team in communications with the umpire and the opposing team. A player may be designated as head coach in the event the head coach is absent.
a. The head coach may delegate specific duties prescribed by the rules to a player or assistant coach, and any action of such designated representatives shall be official. The head coach always shall be responsible for the team’s conduct, observance of the official rules and deference to the umpire.
b. If a head coach leaves the field, a player or assistant coach shall be designated as the substitute; and such substitute coach shall have the duties, rights and responsibilities of the head coach. If the head coach fails or refuses to designate a substitute before leaving, the umpire-in-chief shall designate a team member as substitute head coach.
