"Days of Our Lives" and "Biggest Loser" star Alison Sweeney will add a peacock feather to her cap this spring, when she guest stars on NBC's hospital drama "Mercy," Entertainment Weekly reports.
The 33-year-old actress is set to play a victim of a bus crash whose minor injuries turn out to be more severe than the staff of Mercy initially realizes.
Sources tell EW.com that the doctors and nurses eventually figure out that Sweeney's character has shrapnel in her brain, which causes erratic behavior.
Sweeney's guest run begins this March.
