If an umpire observes a player wearing illegal protective gear, what action is taken?

When an umpire observes a player wearing illegal protective gear, the appropriate course of action is for the player to be required to comply and replace the gear with legal equipment. This action ensures that all players are adhering to safety regulations and the established guidelines of the game.

Illegal protective gear can pose risks not only to the player wearing it but also to other players on the field. By mandating the replacement of illegal gear, the umpire is maintaining the integrity of the game and ensuring player safety. It is essential for the rules to be enforced consistently to promote fair play and to protect the welfare of all participants.

The other choices would not properly address the situation with appropriate measures for maintaining safety and compliance with game regulations. Awarding a penalty kick or giving a warning without requiring compliance would not effectively address the issue of the illegal gear. Ejecting the player immediately could be considered excessive unless the context of the situation warranted such action. Thus, requiring compliance and replacement of the illegal gear is the correct and standard procedure.
