No. 4 Wisconsin (8-0, 5-0 Big Ten, CFP No. 9 CFP) at Indiana (3-5, 0-5), Saturday, noon ET (ABC)

Line: Wisconsin by 12 ½.

Series record: Wisconsin leads 40-18-2.

WHAT'S AT STAKE?

Wisconsin is one of five unbeaten teams left in FBS, but must keep winning to stay in the playoff hunt because of a weak schedule. Indiana is looking for its first conference win. The Hoosiers last three losses have come by three points, eight points and seven points in overtime.

KEY MATCHUP

Wisconsin's secondary vs. Indiana's receivers. The Badgers lead the Big Ten in scoring defense and are No. 2 in total defense, run defense and pass defense. This week, they face three Indiana receivers — Simmie Cobbs Jr., Luke Timian and Whop Philyor — who caught 10 or more passes last week.

PLAYERS TO WATCH

Wisconsin: RBs Jonathan Taylor and Garrett Groshek. Taylor, a freshman, leads the Big Ten in rushing (148.1 yards per game) and TD runs (11). But he's fighting through an injured left leg and if Taylor can't play, the Badgers probably will turn to the redshirt freshman, Groshek.

Indiana: QB Peyton Ramsey. The redshirt freshman has been solid, tough and gives the Hoosiers' offense a different dynamic with his legs. But he left last week's game with an apparent knee injury. Fifth-year senior Richard Lagow, the former starter, must be ready just in case.
