Ohio State used a fourth-quarter rally to escape Iowa with a victory Saturday and, as a result, the Buckeyes moved up one spot to No. 8 in the latest BCS rankings.
Nebraska, which lost to Texas A&M, fell to No. 15 from No. 8, allowing OSU to creep closer to No. 7 Wisconsin. The Badgers hold the inside track on an invite to the Rose Bowl. Wisconsin, OSU and Michigan State are tied for first in the Big Ten with just one conference loss. In the event of a three-way tie at the end of the regular season, conference rules state that the tiebreaker goes to the team ranked highest in the BCS.
Oklahoma State moved up to No. 9 from No. 10 and Michigan State jumped Alabama to sneak into the top 10. The Spartans were ranked No. 12 last week.
The rest of the top 10 remained intact. Oregon, Auburn and TCU stayed at No. 1, No. 2 and No. 3, respectively, after all three teams had a bye week. Boise State remained at No. 4, LSU stayed at No. 5 and Stanford held at No. 6.
Wisconsin hosts Northwestern on Saturday, while the Buckeyes play rival Michigan at Ohio Stadium.
