No. 4 Ohio State (4-0)
Next game: September 29 at Penn State
Ohio State has one ranked win against TCU this year, but a top-10 road game against the Nittany Lions will determine who has the leg up to make it out of the East Division to the Big Ten championship game.
No. 5 Oklahoma (4-0)
Next game: September 29 vs. Baylor
Oklahoma just barely made it past Army with its undefeated season intact. The Sooners walked away with a 28-21 overtime win. Oklahoma's next true road game is on Oct. 20 at No. 17 TCU.
No. 6 LSU (4-0)

No. 8 Notre Dame (4-0)
Next game: September 29 vs. Stanford
The Fighting Irish won convincingly at Wake Forest, 56-28, to move to 4-0. Now the Irish have an extremely difficult two weeks with a home game against Stanford followed by a road game at Virginia Tech.
No. 10 Penn State (4-0)
Next game: September 29 vs. Ohio State
After a scare against Appalachian State in Week 1, the Nittany Lions have blown out Pittsburgh, Kent State, and conference opponent Illinois. while Trace McSorley has thrown for eight touchdowns, but has completed just over 50 percent of his throws. With their first Big Ten matchup behind them, Penn State now has No. 4 Ohio State and No. 24 Michigan State at home.
No. 12 West Virginia (3-0)
Next game: September 29 at Texas Tech
After a week off due to Hurricane Florence washing out the Mountaineers game against NC State, Will Grier and West Virginia poured it on Kansas State in a 35-6 victory.
No. 16 UCF (3-0)
Next game: September 29 vs. Pittsburgh
McKenzie Milton has been unstoppable through three games for the Knights. He has thrown for 895 yards and nine touchdowns and scored a total of six touchdowns in Week 4 against Florida Atlantic.
Next game: September 29 vs. Army
The Bulls dismantled the Rutgers Scarlet Knights on the road, 42-13, behind three passing touchdowns by Tyree Jackson.
Next game: September 29 vs. Oregon
Cal took an early lead just under three minutes into the first quarter, and drove that lead home with three more touchdowns before the half. A last-quarter surge from Idaho State wasn't enough to overcome the undefeated Bears.
Next game: September 29 at UConn
The Bearcats outscored the Ohio Bobcats 13-3 in the fourth quarter to win 34-30 and remain unbeaten. Cincinnati has three of its next four games on the road.
Next game: September 28 vs. UCLA

Next game: September 29 vs. Virginia Tech

Next game: September 29 vs. University of South Carolina
The Wildcats knocked off Florida in Week 2 for the first time since 1986 and followed that up with a 48-10 win against FCS opponent Murray State. Now, Kentucky has taken down No. 14 Mississippi State in decisive fashion, 27-7.
NC State (3-0)
Next game: September 29 vs. Virginia
A case could be made for NC State to potentially be among the group of remaining undefeated teams in October given that five of the Wolfpack's first six games are at home. After beating James Madison and Georgia State in the first two weeks, the Wolfpack were supposed to host West Virginia, but Hurricane Florence prevented that game from being played. The Wolfpack have now taken down Marshall, 37-20, and will host Virginia next.
North Texas (4-0)
Next game: September 29 vs Louisiana Tech
It may have gone under the radar but North Texas arguably had one of the more impressive wins in Week 3 as the Mean Green went to Arkansas and beat the Razorbacks 44-17, with the help of a fake fair catch punt return that went 90 yards for a touchdown. This week, North Texas took down Liberty in a 47-4 routing to continue its undefeated season.
South Florida (4-0)
Next game: October 6 at UMass
The Bulls head into their Bye week at a perfect 4-0 after defeating East Carolina 20-13.
