The worlds of Law & Order and Chicago Justice are about to collide.

Lorraine Toussaint is set to appear in the backdoor pilot of Dick Wolf's latest NBC drama as a character she originated on the former series 26 years ago, The Hollywood Reporter has learned.

The Critics Choice Award winner will play defense attorney Shambala Green in the 21st episode of Chicago P.D., which serves as the backdoor pilot for Chicago Justice. Formerly titled Chicago Law, the show stars Philip Winchester, Nazneen Contractor, Joelle Carter and Carl Weathers, the latter's casting was announced Saturday at PaleyFest.

Toussaint played Green seven times over Law & Order's 20 seasons, her most recent appearance being in 2003. Since then, Toussaint has enjoyed breakout success thanks to her role as Vee in Orange Is the New Black. The actress currently stars on the Fox medical drama Rosewood. Her appearance in the Chicago Justice pilot is a guest-starring role, meaning her full-time gig on Rosewood will not be affected. The actress, whose other credits include The Fosters and Selma, is repped by Innovative Artists, Frontline Management and Del Shaw.

This is not the first time the Chicago franchise has pulled from the Law & Order catalog. S. Epatha Merkerson, who played Lt. Anita Van Buren for 17 seasons on the flagship drama, now plays a different character on Chicago Med. However, Chicago Fire and Chicago P.D. have crossed over with the cast of spinoff Law & Order: SVU.
