Michigan QB Ryan Mallett throws a pass, while OL Steve Schilling holds his block on Wisconsin pass rusher Matthew Shaughnessy, who had two-and-a-half sacks. Mallett took over in the first half for injured starter Chad Henne and struggled, completing just 11 of 36 passes for 245 yards, three touchdowns and two costly interceptions.
