ANN ARBOR, Mich. — Wilton Speight threw for 253 yards and two touchdowns in three quarters before watching No. 3 Michigan finish off Illinois 41-8 Saturday.

The Wolverines (7-0, 4-0 Big Ten) were leading 34-0 in the fourth quarter when Jim Harbaugh put backup quarterback John O'Korn in the game and rested Speight.

The Fighting Illini (2-5, 1-3) were relegated to starting their third-string quarterback with a familiar name. Jeff George Jr., son of the former Illinois and NFL quarterback, was 4 of 15 for 95 yards with a TD, an interception and a fumble in his first start. The redshirt freshman played because Wes Lunt and Chayce Crouch are injured.

Speight, who completed 16 of 23 passes, threw a 3-yard TD pass to Jake Butt and a 21-yard pass to Tyrone Wheatley Jr. for a score in the first quarter. Khalid Hill's ninth touchdown and De'Veon Smith's 4-yard run gave the Wolverines a 28-0 lead after their first four possessions.

After Michigan botched a fake punt near midfield in the fourth quarter with a 34-0 lead, George threw a 43-yard TD pass to Malik Turner on the next snap and followed with a 2-yard conversion pass to Zach Grant.

Karan Higdon scored on a 45-yard run on the ensuing possession and finished with 106 yards rushing on just eight carries for the Wolverines.
