With the Crimson Tide facing its biggest deficit of the season, Josh Jacobs then recovered his own fumble in the end zone to cut the Bulldogs' lead to 21-14 going into halftime. Jacobs set up the 1-yard TD with a 59-yard burst.
Both teams are playing like there is a spot in the College Football Playoff on the line — because it is.

UAB will head to a bowl game 10-3.

Jake Fromm hit Isaac Nauta for a 20-yard touchdown to take a 7-0 advantage with 3:08 left in the first quarter of the SEC championship game in Atlanta.
The Crimson Tide had only fallen behind once before, when Mississippi scored a 75-yard touchdown pass on the first play of the game. Alabama trailed for just 70 seconds before tying the game. Alabama ended up winning that game 62-7 and has beaten every opponent by at least 22 points.
Alabama quarterback Tua Tagovailoa went into the medical tent after the first series of the SEC championship game in Atlanta.
Tagovailoa, who has battled a right knee injury the past few weeks, appeared to twist his left ankle and seemed to be limping after a sack. But after being evaluated, he was jogging along the Alabama sideline.
Regarded as the Heisman Trophy front-runner, Tagovailoa was intercepted at the goal line by Richard LeCounte on the next play. Tagovailoa came into the game with 36 touchdowns and just two interceptions.

Oklahoma's defense, of all things, came through with a game-changing play against Texas in the Big 12 championship. After the Longhorns forced a turnover to give the ball back to the offense deep in its own territory, the Sooners' Tre Brown sacked Texas quarterback Sam Ehlinger in the end zone for a safety to make it 32-27.

Big 12 officials said it is the biggest crowd ever for a Power Five championship game. The previous record was 83,091 for the inaugural SEC championship game at Legion Field in Birmingham, Alabama.

Those games are at Cotton Bowl Stadium, where there was a sold-out crowd of 92,300 when they played eight weeks a

The Sooners have scored at least 45 points in eight straight games.
Oklahoma is trying to secure its fourth straight Big 12 title and third appearance on the College Football Playoff.
Big 12 Commissioner Bob Bowlsby knows there's no guarantee No. 5 Oklahoma will get into the College Football Playoff with a win in the Big 12 title game, even if Georgia loses to Alabama in the SEC championship game.
Asked before Saturday's title game if he was comfortable that the Sooners would get into the four-team playoff with a win over No. 9 Texas, Bowlsby responded, "No."
The Sooners are fifth in the latest CFP standings, behind Alabama, Clemson, Notre Dame and Georgia. Ohio State, which is sixth, plays Northwestern in the Big Ten championship game Saturday night.
"I think the human nature being what it is, I think the last thing you see makes a lot of difference, and I don't think it's inconceivable that Ohio State could win big and they could jump," Bowlsby said.
"I don't think that's as likely as it might have been before Tuesday (and the latest CFP ranking) because there's the talk about the strength of schedule and OU's strength of schedule is going to do nothing but get stronger by this," Bowlsby said. "And chances are if Ohio State beats Northwestern, chance are Northwestern may fall out of the Top 25, so that would further weaken the strength of schedule."
In the first year of the CFP in 2014, Ohio State won the Big Ten championship game 59-0 and took the fourth playoff spot ahead of Big 12 co-champions TCU and Baylor.
Less than four minutes into the Big 12 championship game, the first of four Power Five title contests on Championship Saturday, No. 9 Texas has a touchdown and a 7-0 lead against No. 5 Oklahoma.
The Sooners have allowed at least 40 points in each of their last four games and won them all, a first in college football history. But their high-scoring offense led by quarterback Kyler Murray still has Oklahoma in position for a College Football Playoff appearance.
Before the College Football Playoff field is set, there is one last chance to make a case to the selection committee.
No. 5 Oklahoma and No. 6 Ohio State both need to win Saturday — and they should both be rooting for Alabama.
The Sooners enter Championship Saturday with a chance to make the playoff for a second straight season. Oklahoma faces archrival Texas for the Big 12 title in the first of four Power Five championship games that will decide the four-team playoff field that will be revealed Sunday.
Ohio State plays Northwestern in the Big Ten championship. No. 1 Alabama faces No. 4 Georgia for the SEC title and a win by the Crimson Tide could open the door for the Sooners or Buckeyes. No. 2 Clemson is heavily favored against Pittsburgh in the ACC championship game.
In all, there are nine championship games on Saturday: Besides the SEC, ACC, Big Ten and Big 12 games, titles will be settled in the Sun Belt (Louisiana-Lafayette at Appalachian State), Conference USA (UAB at Middle Tennessee), American Athletic (Memphis at UCF), the SWAC (Southern at Alcorn State) and the Mountain West (Fresno State at Boise State).
