Final answer:
Yes, it is generally true that a player or coach who physically contacts a game official in dissent of a call shall be ejected. Respect for officials is critical, and sports organizations enforce strict penalties for such actions.
Step-by-step explanation:
The statement regarding a player or coach physically contacting a game official in dissent and facing ejection is generally true. Sports leagues and organizations have rules in place to maintain respect for game officials and ensure the safety of everyone involved. Contacting an official in disagreement with a call is seen as a serious offense. Thus, any physical altercation with an official, whether intentional or accidental, can lead to the immediate ejection of the player or coach in question, and potentially further disciplinary actions could be taken, depending on the severity of the incident and the governing body's rules.
