Davis Mills has taken over at QB for the second half. The quarterback switch comes after K.J. Costello took a brutal hit to the head from Northwestern’s Earnest Brown:

No targeting penalty was called. Costello is out for the second half, presumably with a concussion.
On Mills’s first drive, he turned over the ball on a fumble.
