MADISON, Wis. — Wisconsin is getting backup quarterback Jack Coan ready to play this weekend at No. 21 Penn State with starter Alex Hornibrook listed as questionable because of another head injury.

Hornibrook was in the concussion protocol for the second time in three weeks after getting hurt in last week’s 31-17 victory over Rutgers. Hornibrook’s head hit the turf after being sacked on the last play of the first half.

Coan was 20 of 31 for 158 yards and a touchdown in a 31-17 loss at Northwestern two weeks ago, which was his first career start.

“I don’t think it’s easy any time you go on the road in the Big Ten to have that as your first experience,” offensive coordinator Joe Rudolph said after practice Tuesday. “It could be something that you can grow tremendously from or it can be something that can stagnate you.”

Coan, a sophomore who won the Hansen Award as a senior at Sayville High School in 2016, was 5 of 7 for 64 yards and a score in relief of Hornibrook last week. Hornibrook, a third-year starter, struggled in the first half and threw two interceptions.

The Badgers may need to prove that they can move the ball through the air with Coan against a tougher defense on the road, though they also successfully ran the ball for all 13 plays of the third quarter against Rutgers.

“When he got the opportunity to go in this past week, I thought he showed some growth,” Rudolph said about Coan. “It’s tough right now. We all want Alex to be healthy, but we all know that guys have got to step up at any position.”
