According to TV Guide, Knight will guest star on a fall episode of 'Law & Order: SVU' as a "serial rapist who consistently maintains his innocence despite overwhelming evidence." There's not yet an airdate for the episode.
'SVU,' the lone series left on the air from Dick Wolf's 'Law & Order' franchise, has been beefing up its cast for this season's very special episodes. Kyle MacLachlan has signed on as a Schwarzenegger-esque lothario, while former ADAs Stephanie March and Diane Neal will return to help new cast members Danny Pino and Kelli Giddish adjust to life in the Special Victims Unit.
Since leaving 'Grey's' in 2009 after years worth of drama -- co-star Isaiah Washington left the show in 2007 after making public remarks about Knight's sexuality -- Knight has starred in a Los Angeles production of the musical 'Parade' and the 2010 Broadway revival of David Mamet's play 'A Life in the Theatre.'
