The Cougars jumped 11 spots to No. 9 in the Top 25 released Tuesday, three days after they stunned Oklahoma 14-13 as three-touchdown underdogs.
Cougars quarterback Max Hall said the victory has energized Provo, Utah, and the BYU campus.
"For the first time there were people at the airport to greet the team. About 2,000 people were out there when we got back," he said.
Florida was still an overwhelming No. 1, receiving 56 of 60 first-place votes, two less than last week.
No. 5 Oklahoma State moved up four spots after an impressive 24-10 victory against Georgia. The loss dropped the Bulldogs eight spots to No. 21.
Georgia Tech remained 15th.
