Jeremy Sisto joins the esteemed cast of NBC's Emmy Award-winning drama "Law & Order," as it returns for its 18th season on Sundays beginning in January 2008. Sisto will play veteran Detective Ed Green's (Jesse L. Martin) new partner.

The Chicago native began his theatrical career early when he appeared onstage at the Goodman Theater in a production of Tennessee Williams' last play, "A House Not Meant to Stand," as well as Bertolt Brecht's "Galileo," opposite Brian Dennehy.
