Tolbert (coach's decision) is listed as inactive Sunday at the Rams, Todd Archer of ESPN.com reports.
Through the first five games of his career, Tolbert has made just one appearance to date. With the rookie third-round pick again in street clothes, the Cowboys' receiving corps will be composed of CeeDee Lamb, Michael Gallup, Noah Brown, Simi Fehoko and KaVontae Turpin.
