The rain-soaked conditions at Leonard Cole Field have prompted the Marshalltown High School athletic department to cancel tonight's sophomore football game between Marshalltown and Fort Dodge, paving the way for a varsity-only contest between the CIML Iowa Conference rivals. The game to decide the conference championship starts at 7:30 p.m., with the gates opening at 6:30 p.m. Class 4A fourth-ranked Marshalltown (8-0, 4-0) and the eighth-ranked Dodgers (7-1, 3-1) match up in WHO-TV's 'Game of the Week'.
