Entering Saturday night, all No. 7 Alabama needed was a win over unranked Oklahoma to stay very safe in the College Football Playoff bracket.
Earlier in the day, No. 5 Indiana was knocked out, No. 4 Penn State barely squeaked by Minnesota, and No. 9 Ole Miss and No. 14 BYU were both lost.
But the Crimson Tide couldn't get the job done, as Oklahoma dominated to a 24-3 victory.

Alabama's Jalen Milroe, who had been one of the best players in the country, had his worst game of the season. He completed 11 of 26 passes for 164 yards with three interceptions and gained just seven yards on 15 carries for Alabama (8-3, 4-3). The Sooners held Alabama to 234 yards. He was just 2 of 7 for 62 yards before halftime.
True freshman Xavier Robinson ran for career highs of 107 yards and two touchdowns as Oklahoma became bowl eligible and took coach Brent Venables out of the hot seat.
The Sooners' victory resulted in another edition of fans storming the field too early, but at least this one was mostly over anyway, unlike the BYU-Arizona State game.

Ole Miss and Alabama, both in last week's predictions, now have three losses this season. That leaves the door wide open for 9-2 teams like Clemson and Iowa State, ranked 17th and 22nd in the country, respectively.
And now Indiana's College Football Playoff hopes, fresh off the end of their undefeated season, might not be over. No. 10 Georgia and No. 11 Tennessee are expected to move up a few spots with three teams ahead of them in the rankings, all losers.
However, it's certainly not out of the question that Alabama could be on the outside looking in.
