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 in his first career start. Offensive coordinator Joe Rudolph says Coan has grown from that experience as he prepares for another potential road start.
The sophomore was 5 of 7 for 64 yards and a score in relief of Hornibrook last week.
