Knight will guest-star on NBC’s Law & Order: SVU, TVLine has confirmed, playing a suspected serial rapist. Knight’s episode is currently in production, says TVGuide.com (which first reported on the casting); no air date has been set.
Since negotiating his exit from Grey’s two years ago — following much backstage tension after costar Isaiah Washington directed an anti-gay slur at him — Knight has focused on stage work, including a fall 2010 run in Broadway’s A Life in the Theatre, opposite Patrick Stuart.
On Grey’s, he earned an Emmy nomination in 2007, for his portrayal of Dr. George O’Malley.
SVU kicks off its 13th and rather transitional (given a flurry of cast changes) season on Wednesday, Sept. 21 at 10/9c.
