Sarah Chalke is scrubbing in to yet another hospital.

The actress, who helped anchor Scrubs for eight seasons and has since appeared on Cougar Town and Mad Love, will guest star on an upcoming episode of Grey's Anatomy Season 9.

TV Line broke this casting news, though details on Chalke's role are unknown at this time. We'd have to assume she plays the Patient of the Week on the ABC drama.

The actress will lead a new sitcom on the network this spring as well: How to Live with Your Parents premieres Wednesday, April 3.
