Nebraska's Ameer Abdullah, the nation's No. 3 rusher, left Saturday's game against Purdue in the first quarter with a knee sprain.
Abdullah left with one yard on six carries, and Nebraska coach Bo Pelini said after the game that Abdullah's MCL sprain was "mild."
Abdullah -- who reminds NFL Media analyst Mike Mayock of the Cincinnati Bengals' Gio Bernard -- came in with 1,249 yards and 17 touchdowns on the ground, and he had a streak of five consecutive games with at least two rushing touchdowns. He also has had four 200-yard games.
Nebraska is off next week, then plays at Wisconsin on Nov. 15. The Huskers need Abdullah if they're to have any shot at beating the Badgers.
