ESPN projections give Nebraska a 2.1-percent chance of going undefeated.
Of the nine remaining undefeated FBS teams, ESPN writer Brian Fremeau's calculations give Nebraska the least likely shot of finishing the season without a loss.
The Huskers have a six-percent chance of beating both Wisconsin and Ohio State over the next two weeks, according to ESPN. The projections show that Nebraska has a 56-percent chance of dropping both of its next two games and a 44-percent chance of losing three of its final five.
On the flip side, Big Ten power Michigan holds a 57.8-percent chance at finishing the regular season with an unblemished record.
