The Cornhuskers will not participate in a bowl game for the third time in 48 seasons and have lost four consecutive home games for the first time since 1968 and 1969.
Riley's demise accelerated in September when Shawn Eichorst -- the athletic director who brought Riley to Nebraska -- was fired after the Huskers lost 21-17 to Northern Illinois.
University leaders said at the time that Eichorst's efforts had not produced adequate results in football and that they were not pleased with Nebraska's competitiveness.
Soon after, Riley's team nosedived, losing 38-17 to Wisconsin and 56-14 to Ohio State in consecutive weeks at Memorial Stadium.
Moos was hired as athletic director from Washington State in mid-October. Nebraska won 25-24 at Purdue in Week 9 but closed with the four-game skid that included losses to Minnesota, Penn State and Iowa in which it allowed 166 points and 9 yards per play.
