Down goes another one of college football's unbeaten.

Oklahoma's shocking home loss as a four-touchdown favorite against Iowa State moves the previously third-ranked Sooners out of the Top 5 in Sunday's Week 7 Amway Coaches Poll as Lincoln Riley's squad slid all the way to No. 12.

Alabama remained at No. 1 following its hard-fought 27-19 win at Texas A&M, the Crimson Tide's 20th consecutive victory vs. SEC competition.
