Wisconsin quarterback Russell Wilson had the Badgers in title contention through six weeks.
The Badgers (6-1, 2-1 Big Ten) were ranked No. 4 in the AP Top 25 and No. 6 in the BCS standings.
Wilson had 1,557 passing yards for 14 touchdowns and one pick at one point this year.
The senior, though, had a rough game against No. 9 Michigan State (6-1, 3-0). Wilson was 14-for-21 for 223 yard and two touchdowns, but the Spartans picked Wilson off twice.
His Badgers lost 37-31, effectively ending their title hopes.
Wisconsin dropped to No. 12 in the AP polls and No. 15 in the BCS standings.
