9-1-1: Nashville Adds Grey’s Anatomy’s Jessica Capshaw — Who Is She Playing?

ABC‘s 9-1-1 spinoff just snagged another high-profile TV star.

Jessica Capshaw, best known to TVLine readers for starring as Dr. Arizona Robbins (aka one half of #Calzona) on Grey’s Anatomy, has been tapped to star alongside Chris O’Donnell in 9-1-1: Nashville, our sister site Deadline reports.

No official character details are available for Capshaw’s character, though she is believed to be the wife of O’Donnell’s Captain Don Sharpe, who is described as “a rugged fire captain and rodeo rider who runs Nashville’s busiest firehouse with his beloved son. Don’s a devoted husband and family man but he has his secrets.”

Though an official premiere date has not yet been set, 9-1-1: Nashville has received a straight-to-series order and is expected to air sometime in the 2025–2026 TV season. It will not have a backdoor pilot in the current season of 9-1-1, nor is it expected to feature any characters from either the flagship series or its short-lived Fox spinoff 9-1-1: Lone Star.

Capshaw scrubbed in for more than 200 episodes of Grey’s Anatomy, between her 2009 debut and most recent appearance in 2024. Additional TV credits include roles on Bones, ER, The L Word, The Practice and Tell Me Lies, among other series.

Neither ABC nor 20th Television have confirmed Capshaw’s casting. Thus far, only she and O’Donnell have had their names publicly attached to the spinoff.
