MADISON, Wis. — Alex Hornibrook remains the starter at quarterback for No. 8 Wisconsin, which has also used backup Bart Houston more behind center of late.

More Badgers coverage

Coach Paul Chryst said Monday that Hornibrook will start on Saturday at Northwestern. Hornibrook took over as starter in the Week 4 win at Michigan State.

But Chryst gave Houston a couple series two weeks ago against Iowa. Houston got a few more drives in last week’s win over Nebraska , including the series in overtime that led to Dare Ogunbowale’s 11-yard touchdown run for Wisconsin (6-2, 3-2 Big Ten).

Hornibrook has played relatively well for a redshirt freshman, though he has six interceptions in five starts. The left-handed thrower has shown poise in the pocket.

Houston offers a change of pace with more mobility. Chryst has said he’ll need both quarterbacks moving forward.

Also Monday, the Big Ten named Ryan Connelly its co-Defensive Player of the Week, along with Indiana’s Marcus Oliver.

Connelly had 11 tackles, including 2 1/2 for losses, against the Cornhuskers. He started for leading tackler Jack Cichy, who is out for the year with a torn pectoral muscle.

The Badgers face more questions on defense with starting outside linebacker T.J. Watt listed as questionable with a right shoulder injury. He got hurt against Nebraska but did return to the game.

Nose tackle Olive Sagapolu has already been ruled out for a third straight game with a right arm injury.
