Injured Batter

[blueskysblue]

Help, please!

High School, FED Rules. Batter swings at a pitch, takes a hard pitch on the fingers. Strike called, batter told to remain in the box. Batter unable to continue, due to finger injuries. No eligible subs available.

I have found the rule that discusses a runner unable to continue when there are no eligible subs available. I cannot find anything about an injured batter.

Thanks for your help.
