When can Team A continue to play with only eight players after an injury?

The situation allows Team A to continue playing with eight players as long as they declare an out when the turn comes for the injured player. This rule provides flexibility for teams facing unexpected injuries during a game, allowing them to maintain competition rather than being forced to forfeit or cease playing.

By declaring an out for the injured player, the team acknowledges the absence while still being able to contribute to the game with the remaining players. This approach ensures the continuation of the game in an orderly fashion and reflects the rules set forth by the governing body regarding roster sizes and player participation.

Other options do not support the continuity of play without the need to declare outs or provide specific conditions that don't align with how the rules are typically enforced. For instance, specifying that the allowance is limited to the first inning or contingent upon having substitutes or a doctor's note does not capture the broader principle that teams can indeed continue playing while managing the consequences of an injury with the declaration of an out.
