Sherry Stringfield is trading in her white coat for an investigator's badge.
The long-time ER star will appear on an upcoming episode of CSI, according to TV Line, coming on board the drama as a "blue-collar swing shift CSI" named Dawn who joins Elisabeth Harnois' Morgan on a serial rape case.
Look for the character to also have a son at home with an addiction problem.
Stringfield has mostly avoided the small screen since scrubbing out of ER in 2009, appearing later that same year on an episode of Curb Your Enthusiasm.
Her CSI installment will air some time this fall.
