Which of the following are examples of non-injury grievances?

The correct choice highlights that challenging fines or suspensions is an example of a non-injury grievance. In the context of the NFL, non-injury grievances involve disputes that arise from administrative actions or decisions made by the league or teams that do not pertain to player injuries. These can include issues related to disciplinary actions, such as fines and suspensions, which players may feel are unwarranted or unjust.

Injury grievances, which are not the correct answer, specifically deal with disputes or claims related to players' injuries and how they affect contracts or compensation. Contract negotiations, while a form of grievance, can be classified as a different category of disputes and do not fall under the non-injury grievances if they involve negotiations over terms rather than challenges to decisions already enforced. Finally, position changes would more likely pertain to roster decisions or coaching strategies and do not typically qualify as grievances.

Thus, the essence of non-injury grievances centers around disputes that are not related to physical injuries, making challenging fines or suspensions a clear example.
