Robinson, who leads the Hawkeyes (No. 20 BCS, No. 21 AP) with 914 yards rushing and 10 touchdowns, entered the game early in the second quarter.
Freshman Marcus Coker started in place of Robinson and ran for 43 yards in the first quarter.
Robinson missed Iowa's win over Indiana on Nov. 6 because of a mild concussion. He returned and rushed for 108 yards in last week's 21-17 loss at Northwestern.
