Re-entry Rules: Can a Player Return After an Injury?

Question
If a player had a (example) sore arm and was sat for an inning, after a little while in the game can he/she be let back in the game if there arm is better?

Answer
Hi Emily,

If she was subbed for and has a re-entry left, (any player can re-enter once, sure she can sub back in to her her original batting position.

If she left the game and you had to play "shorthanded" because you didn't have a legal sub available, no she cannot just because of a sore arm or whatever.  If she left because of the "blood rule" she can return.
