WHAT'S AT STAKE

Both teams are trying to shake off stinging losses to Ohio State and avoid a two-game skid in the Big Ten. The Wildcats can still keep pace in the Legends Division with a victory. The Badgers are coming off a bye but face a steeper challenge after losing to the Leaders Division rival Buckeyes two weeks ago.

KEY MATCHUP

Northwestern QBs Kain Colter and Trever Simien vs. Wisconsin LBs. Really, Colter is more than just a quarterback, and Northwestern's offensive scheme can confound opponents. But the Badgers have one of the best linebackers in the country in Chris Borland, a heady player who can figure things out quickly. The linebackers may have to adjust on the fly to mismatches to contain Northwestern.

PLAYERS TO WATCH

Northwestern: Colter. Simien has thrown for more yards, but Colter always draws attention by where he's lining up if he's not the only quarterback on the field. Last week Colter caught his first pass of the season — a touchdown — to go with his fourth rushing score. Oh — he was 12-for-12 passing for 98 yards, too.

Wisconsin: RB Melvin Gordon left the Buckeyes game two weeks ago with a left knee scare. Turned out to be just fine. But the Big Ten's leading rusher (139.6 yards per game) has been peppered with questions since then about whether he's OK. He can prove it on the field Saturday.
