Martha Plimpton to do 'Grey's' arc

Martha Plimpton has been tapped for a multi-episode arc on ABC's "Grey's Anatomy."

Starting with the season premiere of "Grey's," Plimpton will appear as the mother of a young patient.

The upcoming sixth season of "Grey's" premieres Sept. 24.

Plimpton, who received a Tony nomination this year for "Pal Joey," is repped by Innovative and Impression.

On TV, she previously recurred on another medical drama, NBC's "ER."
