Series record: Ohio State leads 8-1.

WHAT’S AT STAKE?

The one-loss Buckeyes have no margin for error in their quest to return to the College Football Playoff. Nebraska has lost three straight and five of six, but it has shown an ability to keep it close against top opponents. Just ask Oklahoma, Michigan State and Michigan. Cornhuskers coach Scott Frost is on the hot seat, and his players might be motivated to play for his job.

KEY MATCHUP

Ohio State’s defensive line against Nebraska’s offensive line. The strength of the Buckeyes’ defense is up front, and the line is playing some of its best football. Ohio State leads the Big Ten and is second among Power Five teams with 28 sacks, though nine came against Akron. Nebraska’s offensive line has been mediocre at best and will determine whether the Huskers keep it close or get blown out.

PLAYERS TO WATCH

Ohio State: Freshman RB TreVeyon Henderson has been overshadowed in the Big Ten by Michigan State’s Kenneth Walker III. Henderson is averaging a league-best 7.9 yards per carry, is second to Walker at 106 yards per game and has scored 12 touchdowns. He also is coming off a 152-yard night against Penn State.

Nebraska: QB Adrian Martinez played one of his worst games in a loss to Purdue last week, completing less than half his passes and throwing four interceptions. Martinez is the Huskers’ No. 1 running threat, and he’s hurt the Buckeyes with his legs the past couple years.
