Under what condition does a player's contract toll?

A player's contract tolls when they are placed on the Non-Football Injury (NFI) list. This means that the time the player spends on the NFI does not count against the length of their contract. The tolling of a contract is designed to protect the player's contractual rights when they are unable to perform due to an injury that occurred outside of the team’s activities.

In this case, if a player is put on the NFI list, their contract is essentially paused, and this gives the player the opportunity to recover without negatively impacting their contractual obligations. This situation is distinct from trades, offseasons, or pay cuts, as those circumstances do not lead to a tolling effect on the contract duration in the same way that being placed on the NFI does.
