CHAMPAIGN—itzgerald Toussaint ran for 192 yards and a touchdown and backup quarterback Devin Gardner threw a key TD pass to lead No. 22 Michigan past Illinois 31-14 on Saturday.Starting quarterback Denard Robinson scored two rushing touchdowns, but didn’t play after a big third-quarter hit. Details about his injury weren’t available. In relief, Gardner hit Martavious Odoms for a fourth quarter touchdown that gave Michigan (8-2, 4-2 Big Ten) a 24-7 lead after Illinois scored. The Illini (6-4, 2-4) for the fourth week in a row didn’t score in the first half and, after opening 6-0, they’ve lost four straight.The game, even at halftime, felt like blowout. Illinois (6-4, 2-4) had 30 yards of offense at the half, including minus-12 on the ground, and not one point on the board. They didn’t move the ball into Wolverines territory until late in the third quarter.And still, thanks to their defense, a missed field by Michigan goal and a touchdown by Robinson called back by the officials, the Illini were in the game at 17-0 when quarterback Nathan Scheelhaase drove them deep into Michigan territory late in the third quarter. Scheelhaase gave Illinois life it might not have deserved, running in from the 14 with 19 seconds left in the quarter. Scheelhaase sold a strong fake that gave him room to run outside and, at 17-7, Illinois had its first points and a shot. But the Wolverines responded.After a quick stop by Illinois’ defense, J.T. Floyd picked Scheelhaase off and returned it 43 yards. From the nine, Gardner found Odoms and the margin was back to 17. Ilinois answered with an 18-play drive that took 6:08 off the clock, capped by Jason Ford’s 1-yard run with 3:50 to play. Michigan answered with a score of its own 40 seconds later, when Toussaint ran it in from 27 yards out following a failed onside kick. Then, it was finally over. Michigan missed plenty of chances to put the game away early, while Illinois responded with mistakes of its own. Each team had three turnovers, and two came in the final six minutes of the first half, during a quick series of possessions that ultimately went nowhere. Robinson, after hitting Kevin Koger on a 40-yard pass, ran for what the officials initially ruled was an 8-yard touchdown. But replays showed Robinson stepped out near the 2-yard line and the officials called it back. On fourth and 1, a low snap appeared to slow Robinson in the backfield and Michael Buchanan dragged him down for a loss. But Ford dropped the ball on the next play and Michigan’s Thomas Gordon recovered it at the Illini 13.Three plays later, Whitney Mercilus sacked Robinson and knocked the ball loose. Tavon Wilson recovered it with 3:55 left in the first half, in the process giving the Illini their best field position of the game to that point at their own 32.Ford appeared to fumble again inside his own 20 with 14 seconds left in the first half, a ball Courtney Avery grabbed and ran into the end zone. But replays showed Ford’s elbow hit the ground before the ball came out, and the officials overturned that call, too, sparing Illinois yet again.With 1:05 left before halftime, Michigan kicker Brendan Gibbons missed a field goal from 36 yards with a stiff wind at his back.He atoned for it early in the third quarter, after Ryan Lankford dropped a third-quarter punt that Michigan’s John McColgan fell on. This time, Gibbons converted on a 26-yard field goal for a 17-0 lead with 4:31 to play in the quarter.As erratic as both teams were, though, Toussaint was a rock. He had 121 yards by the end of the first quarter, and set the tone for the game early.
