The Packers signed Martinez to the practice squad Tuesday.
With MarShawn Lloyd (hamstring) on injured reserve, it seems the Packers would like to bolster their running back room before the upcoming playoff run. The rookie seventh-rounder was waived by the Seahawks at the end of the preseason and has not yet seen action in an NFL regular-season game. Lloyd will be a candidate for elevation if Josh Jacobs, Emanuel Wilson or Chris Brooks were to suffer an injury in the coming weeks.
