On Sunday, the AP college football Poll was revealed. According to Bleacher Report, all of the bottom four teams, in this week's top-25, weren't ranked in last week's poll.

Of course, that also means that four teams have fallen out of the top-25. Here are the four new teams in the AP College Football Poll and the four teams that are no longer ranked.

Newcomers

  • Texas A&M #22

Texas A&M finally put an end to Kentucky's surprising undefeated start with a 20-14 victory in overtime. While the Aggies have lost two games this season, they were against two teams squarely in the playoff picture (#1 Alabama and #4 Clemson).

  • South Florida #23

South Florida remained undefeated by winning a high-scoring affair on Saturday by the score of 58-42 over UMass.

Redshirt junior running back Jordan Cronkrite had a career outing rushing for 302 yards and three touchdowns in the win.

  • Mississippi State #24

On Saturday, Mississippi State was able to shut down then #8 Auburn [VIDEO] by holding them to nine points while putting up 23 of their own. Whether they remain ranked is in question as three of their next four games are against strong SEC competition (at LSU, vs. Texas A&M, and at Alabama).

  • Cincinnati #25

While Cincinnati has not played the most impressive slate of games, they still sit at 6-0 after a 37-21 win over Tulane on Saturday. Towards the end of the season, they have their toughest games on the schedule at home against South Florida and on the road against Central Florida. According to the Cincinnati Enquirer, it is the first time they have been ranked since 2013.

Dropped out

  • Stanford (Last Week: #14)

Stanford was without last year’s Heisman runner-up, running back Bryce Love, for the second time this season on Saturday and was handled by Utah 40-21. The Utes had dropped their first two games in the Pac-12 prior to their upset victory over the Cardinal.

  • Michigan State (Last Week: #20)

Michigan State suffered a disappointing 29-19 road loss to Northwestern on Saturday, a team that was 1-3 entering the game. The season may start going downhill fast for the 3-2 Spartans [VIDEO] as their next two games are at Penn State and home against Michigan.

  • Virginia Tech (Last Week: #24)

Virginia Tech was a hard team to read entering Saturday night's game against Notre Dame. Would they be the team that easily handled two then-ranked opponents in Florida State and Duke? Or would they be the school who lost in arguably the biggest upset of the season at the hands of Old Dominion? The Hokies held ground with the playoff-contending Fighting Irish as they were down just 10-9 at halftime, but they were outscored 28-7 in the second half.

  • Oklahoma State (Last Week: #25)

It was a no-brainer that Oklahoma State would no longer be ranked after losing at home Saturday to a then 1-3 Iowa State team. The Cowboys gave up 48 points to the Cyclones who hadn't scored any more than 27 in their first four games.
