Entering the fourth weekend of Big Ten play, two Big Ten teams remain unbeaten in conference play and both squads will be on the road Saturday. Iowa, off to its first 6-0 start since 1985, will look to improve to 3-0 in conference action with a road matchup at 5-1 Wisconsin, which suffered its first loss last weekend. Four-time defending Big Ten Champion Ohio State is already 3-0 in conference play and will battle Purdue in West Lafayette. Other Big Ten matchups on Saturday include Northwestern at Michigan State, Minnesota at Penn State and Illinois at Indiana, while Michigan wraps up non-conference play against Delaware State.
