Giants release receiver Parker, sign defensive tackle Ellis
Coach Tom Coughlin announced the moves on Tuesday, two days before the winless Giants are to play the Washington Redskins (1-1) at MetLife Stadium.
Parker had five catches for 43 yards in the first two games, but he also had a couple drops.
Ellis was signed as a free agent by the Giants in the offseason and was among the team's final cuts in training camp.
