What is required for a player to validate their contract as stated in Exhibit 6?

In the context of Exhibit 6, the requirement for a player to validate their contract centers around the necessity of completing a physical examination. This is a standard procedure in professional sports contracts, ensuring that a player is in good health and physically able to perform at the required level. The physical exam typically assesses the player's overall fitness and identifies any potential medical issues that could affect their performance or the team's investment.

This validation process is essential, as it protects both the player and the team; it affirms that the player is fit to play and prevents situations where injuries could lead to financial complications or performance liabilities.
