FCS mania continues throughout the Big Ten, and South Dakota continues to be a popular choice for nonconference scheduling.
Northwestern announced Monday it will host South Dakota in 2012, though an exact date has not been determined.
South Dakota also plays Minnesota in 2010 and Wisconsin in 2011. Northwestern has an FCS opponent on the schedule in each of the next four seasons, which won't aid the team's struggles in attendance but should help in the win column.
The Wildcats are upgrading their nonleague schedule during the next few seasons, which is long overdue. The 2012 schedule features home games against both Boston College and Vanderbilt and a trip to Syracuse.
