The Nittany Lions stayed behind Alabama (crushed Ole Miss), Clemson (went to No. 12 Virginia Tech and took down the Hokies, and Oklahoma (bye week).
Penn State is also No. 4 in the Coaches Poll.
Prior to this season, Penn State had not been ranked this high in the AP Poll since 2008.
After starting the season at No. 6, the Nittany Lions jumped to No. 4 in week two before falling a spot after the win over Pitt. It jumped back to No. 4 the next week and has kept that spot since.
It is the longest streak of weeks that the Nittany Lions have spent in the top five since 1999.
Penn State plays Northwestern at Ryan Field next weekend, while the teams ahead of it also play unranked opponents — Alabama at Texas A&M, Clemson against Wake Forest, and Oklahoma against Iowa State.
