(5) Wisconsin 24, (24) Michigan 10
In a hotly contested game in Madison, Wisconsin, the Badgers held off Michigan for their first ever 11-0 record in school history.
Wisconsin started the scoring with a 50-yard punt return for a touchdown from Nick Nelson.
Michigan's Brandon Peters had to be carted off the field in the third quarter after a scary hit from Wisconsin linebacker Andrew Van Ginkel.
Wisconsin put up 325 yards of offence against Michigan's 234. They improved to 11-0, 8-0 in the Big 10 while the Wolverines drop to 8-3 overall, 5-3 in the Big 10.
Wisconsin's next game will be in Minneapolis against the Minnesota Golden Gophers for Paul Bunyan's Axe on Saturday.
Michigan have their traditional rivalry game against the Ohio State Buckeyes at home on Saturday.
Final take on this week's games
Look for a shakeup in the top 3. Clemson's schedule might give Miami, FL an edge, but would still put the two teams against each other in the CFP Semifinal in the Rose Bowl or the Sugar Bowl.
Wisconsin's victory over a Michigan squad might have some leverage over Oklahoma's win against a 1-10 Kansas team.
A team's schedule would be a big factor in who gets selected to participate in this season's College Football Playoff.
There are four teams left undefeated this season, top-ranked Alabama (11-0), 3rd-ranked Miami, FL (10-0), 5th-ranked Wisconsin (11-0) and 15th-ranked Central Florida (10-0). Look for UCF to move up a few spots after 13th-ranked Oklahoma State's upset loss against Kansas State.
