Due to medical issues, American Idol Top 20 contestant Crystal Bowersox is unable to perform on Tuesday's  show.
As a result, the guys will compete on Tuesday night's show, and the women -- originally slated to take the stage Tuesday -- will perform Wednesday.

On Thursday, two guys and two girls will be cut from the competition. Season 8 finalist Danny Gokeywill also perform his new single, "My Best Days Are Ahead of Me."
