The Oregon Ducks have not been underdogs since 2011. Well, that finally changes this week as the Ducks opened as 3.5-point underdogs against Michigan State, according to the Westgate Las Vegas SuperBook.

The Ducks had been favored in 46 consecutive games. The last time the Ducks weren't favored was against Stanford in 2011, a game which the Ducks won 53-30.

Oregon is ranked No. 7 by the Associated Press, while the Spartans are ranked No. 5. The Ducks beat the Spartans in Eugene last season 46-27.
