T.R. Knight is returning to ABC.

The Grey's Anatomy fan favorite has been tapped to co-star in the network's Reese Witherspoon-produced divorce drama, The Hollywood Reporter has learned.

The untitled drama centers on Gemma, a ruthless Dallas divorce attorney whose life begins to unravel when her emotionally damaged, love-addicted sister resurfaces, triggering self-destructive tendencies and exposing long-hidden family secrets.

Knight will play Mark, an associate lawyer at Gemma's firm. He has a jovial sloppiness about him, at least that's what he wants you to? think. He's jockeying for position for partner — same as Gemma — and starts to weasel into her cases.

The casting brings Knight back to the ABC and ABC Studios fold after he spent five seasons on Grey's, where he starred as one of the show's original interns, George "007" O'Malley. The character was killed off after five seasons after Knight — who clashed with former co-star Isaiah Washington — asked to be released a year early from his contract after what he called a "breakdown in communication" with showrunner Shonda Rhimes, lack of screen time and his decision to come out. George's death still ranks as one of the most surprising deaths on Grey's. The role earned him a supporting actor Emmy nomination.

Repped by Gersh and Thruline, Knight is currently co-starring in Hulu's James Franco miniseries 11.22.63. He recently wrapped a run on Broadway in It's Only a Play. The ABC pilot will be his first broadcast series regular role following Grey's, though he has recurred on The Good Wife and guest-starred on Law & Order: SVU.

Meaghan Oppenheimer (Fear the Walking Dead) will pen the script for the untitled divorce drama and exec produce the ABC Studios entry alongside Witherspoon and her Pacific Standard topper Bruna Papandrea.
