Sitting at 2-2 on the season with both losses coming on the road, Michigan's Fitzgerald Toussaint managed to put them in the lead with a 1-yard touchdown rush near the end of the first frame.
It was actually Michigan's first offensive possession, and took them a whopping 17 plays and 78 yards over the course of 8:48. Denard Robinson rushed the ball seven times on the drive, for a total of 24 yards, which explains the high play totals. Toussaint is struggling to pick up big yards, but he's fighting hard for the short ones, and it's paying off in the form of the aforementioned 7-0 lead.
Purdue has had the ball twice, and both were 3-and-outs, ending in Cody Webster punts. The Wolverines took over at the Michigan 37 near the end of the half, and a 38-yard rush by Robinson put them in Purdue territory. A few short plays later, and the first quarter came to an end.
