NEW YORK -- Michigan State moved into The Associated Press college football poll after its thrilling victory against Notre Dame, while No. 14 Arizona received its best regular-season ranking in 12 years after the Wildcats knocked off Iowa.
There was no movement at the top of the rankings Sunday. The top five of Alabama, Ohio State, Boise State, TCU and Oregon was unchanged from last week.
The Crimson Tide received 53 first-place votes, Ohio State got five and Boise State and Texas each received one.
The 25th-ranked Spartans (3-0) used a faked field goal in overtime to beat the Fighting Irish 34-31 and move into the AP Top 25 for the first time since 2008, when coach Mark Dantonio had Michigan State in the rankings for much of the second half of the season.
On Sunday, the school announced Dantonio had a mild heart attack after the Notre Dame game. The 54-year-old was hospitalized Sunday and expected to make a full recovery after undergoing surgery to put a stent in a blocked blood vessel. He is expected to remain in the hospital for at least a few more days and it is unknown how long he will be away from the team.
"This is a time for Spartan Nation to rally around Coach D and the football program," athletic director Mark Hollis said. "We all look forward to his return to the sidelines."
Offensive coordinator Don Treadwell will replace Dantonio during the head coach's absence. Dantonio won't be on the sidelines when the Spartans play Northern Colorado on Saturday.
Arizona is coming off one of its biggest wins in recent seasons, 34-27 against No. 9 Iowa.
The Wildcats were ranked for a few weeks last season, but before that it had been since 2000 that they last made the Top 25.
The last time they were ranked this highly in the regular season was 1998. Arizona finished that season No. 4 in the nation and was in the top 10 for the final six weeks of the season. The Wildcats started the next season ranked No. 4 as well, lost their opening game and quickly fell out of the rankings all together.
Iowa dropped nine spots to No. 18 after its first loss.
Nebraska moved up two spots to No. 6 after dominating at Washington, 56-21. The Cornhuskers are followed by Big 12 rivals Texas and Oklahoma.
Florida is No. 9 and Arkansas moved into the top 10 heading into its biggest home game in decades. The Razorbacks host Alabama on Saturday in Fayetteville.
The second 10 started with Wisconsin, South Carolina, Utah, Arizona and LSU, while Stanford, Auburn, Iowa, Miami and Southern California rounded out the top 20.
The final five were Michigan and star quarterback Denard Robinson at No. 21, with West Virginia, Penn State, Oregon State and Michigan State.
Falling out after its only week in the rankings was Houston, which lost 31-13 at UCLA. The Cougars also lost quarterback Case Keenum to a leg injury in the game, though it is unclear how long he will be out.
