A BASEBALL PLAYER'S COMEBACK IS CUT SHORT WHEN HE BREAKS HIS ARM AND HOUSE AND HIS TEAM HAVE TO ACT FAST TO FIGURE OUT WHAT IS CAUSING MAJOR BONE LOSS THAT'S KILLING THE PLAYER AND HIS DREAMS ON "HOUSE" TUESDAY, FEBRUARY 22, ON FOX

Scott Foley Guest-Stars; Executive Producer Bryan Singer in Cameo Role

A severely broken arm reveals a bizarre case of bone loss and ends the comeback plans of major league pitcher Hank Wiggen (guest star Scott Foley). House suspects Hank - with a history of drug abuse - is lying about using steroids, as his condition worsens. When Hank's kidneys start to fail, his wife offers to donate hers, but she would have to abort her early pregnancy. Forced into an impossible solution, and admitting failure as an addict, Hank tries to take his own life. House and his team must isolate and fix the problem soon if this pitcher's life, as well his career, can be saved in the "Sports Medicine" episode of HOUSE Tuesday, Feb. 22 (9:00-10:00 PM ET/PT) on FOX.
