All of a sudden, Joshua Allen and "Twitch" Boss have more to worry about this week than the So You Think You Can Dance finale on Thursday night.

The pair of finalists was rushed by ambulance to Cedars-Sinai Medical Center after collapsing at a weekend rehearsal.

"The two dancers rushed to the hospital were Joshua Allen and "Twitch" Boss – both [of the] remaining male contestants," a source told Us Weekly.

Boss and Allen were treated for dehydration and released.

They square off off against Katee Shean and Courtney Galiano this Thursday as the show crowns the country's favorite fancer.
