If a rookie does not play due to injury and is on injured reserve, when does their salary for the next year increase?

In the context of NFL contracts, a rookie's salary typically does not increase simply due to their time spent on injured reserve. Instead, contract terms often stipulate that salary increases are associated with active roster participation. If a player is on injured reserve and does not suit up for games, they remain outside the active roster and therefore do not trigger clauses related to salary increases. This means that their contract remains at the same salary level for the duration of their injury-related absence.

When evaluating the other options, it's notable that completing a certain number of games, being on the active roster for a single game, or playing in any game would generally signify participation that could invoke provisions for salary increases. However, if a player is unable to play due to injury, these triggers for increasing salary would not apply and the contract remains unchanged.
