When does an Injury Grievance not apply?

An Injury Grievance does not apply when a player has retired. In this context, once a player officially retires, they are no longer an active participant in the league, and any claims related to injuries sustained while on an active roster become moot. Retired players may lose the rights to file certain grievances or claims for injury-related issues since they are no longer part of the team or subject to the league's labor agreements.

In contrast, players who are on the Physically Unable to Perform (PUP) list or the Injured Reserve (IR) list can still file grievances related to injuries since they are considered to be part of the league and are subject to the terms of their contracts. Also, players who are signed to a team are actively participating in the league, meaning they would typically still have the right to file injury grievances if necessary. Thus, the correct answer highlights the unique situation of retired players in relation to injury grievances.
