CHICAGO – Things to watch this week in the Big Ten Conference:

Game of the Week: Illinois vs. Oregon

No. 20 Illinois (6-1, 3-1 Big Ten) at No. 1 Oregon (7-0, 4-0), Saturday, 3:30 p.m. ET (CBS)

Oregon is ranked No. 1 in the nation for the first time since 2012 as it prepares to host Illinois, which is coming off a 21-7 triumph over Michigan. The Ducks won 35-0 at Purdue last week for their first overall shutout since 2012 and first road shutout since 1992.

Illinois gets a shot at the No. 1 team in the nation just a week after defeating the defending national champion Wolverines. The Illini already have beaten three Top 25 teams this year, the first time they’ve done that since 2007. That 2007 season also included Illinois’ last victory over a top-ranked team – a 28-21 triumph at Ohio State.

BetMGM Sportsbook has Oregon as a 21 1/2-point favorite.

The Undercard: Penn State vs. Wisconsin

No. 3 Penn State (6-0, 3-0) at Wisconsin (5-2, 3-1), Saturday, 7:30 p.m. ET (NBC)

Wisconsin has outscored its last three opponents by a combined 117-16, but it’s hard to figure out what to make of the Badgers’ surge because it’s come against the likes of Purdue, Rutgers and Northwestern.

A much bigger test comes Saturday against Penn State, a 6 ½-point favorite.

Penn State has won its last five meetings with Wisconsin and had last week off, giving the Nittany Lions extra time to prepare. The Badgers are 2-13 in their last 15 games against Top 25 teams, and they’re seeking their first win over a top-five team since beating No. 1 Ohio State in 2010.

Inside the Numbers

The top three FBS quarterbacks in completion percentage are all Big Ten players: Oregon’s Dillon Gabriel (.770), Rourke (.746) and Ohio State’s Will Howard (.733).

His 803 yards receiving rank second among power-conference players, behind the 987 by Mississippi’s Tre Harris. … Michigan State’s Jonathan Kim tied the modern-day Big Ten single-game record by kicking six field goals in the Spartans’ 32-20 victory over Iowa. Michigan’s Jake Moody made six field goals against Indiana in 2018. Purdue’s E.C. Robertson kicked seven against Rose Polytechnic in 1900. … Oregon has won 35 of its last 36 home games.

Upset Watch: Wisconsin vs. Penn State

Wisconsin hasn’t had much success against Penn State lately and has struggled against all Top 25 teams over the last few years, but the Badgers have played much better of late. Penn State showed its road toughness a couple of weeks ago by coming from behind to win at USC, but the Nittany Lions will be dealing with a more hostile environment playing a night game at Camp Randall Stadium. Wisconsin should at least cover the spread and just might win outright.
