However, there are some exceptions to this rule. For example, if a varsity player is injured or sick and unable to play in a varsity game, they may be allowed to play in a JV game instead. In addition, some coaches may allow varsity players to play in JV games for practice purposes or to help develop their skills.
If you are interested in playing in a JV game, it is best to talk to your coach about the rules and policies in your school or state.
