What must happen if a player has blood on his pants at the knee?

If a player has blood on his pants at the knee, the appropriate response is that the pants must be cleaned or changed before he can participate in the game. This rule is in place to ensure player safety and hygiene, as blood can pose health risks to other players and is also a serious concern in maintaining the integrity of the game environment.

In instances of bodily fluid exposure, proper procedures are essential. Cleaning or replacing the contaminated clothing helps prevent the spread of any potential infection and maintains the overall standards of cleanliness required in the sport. Additionally, it aligns with the broader policies of sports leagues that prioritize player health and safety above all.

While players may find themselves in situations where they believe they can continue to play despite minor blood presence, the rules specifically dictate that visible blood must be addressed properly, rather than allowing them to continue playing. This ensures a consistent standard is maintained across all players and games, reinforcing the importance of player health in the sport.
