The Irish (3-0) moved to No. 11 in the AP poll and to No. 15 in the coaches' poll. Notre Dame was No. 20 in the AP and No. 19 in the coaches' poll last week.
The No. 11 ranking in the AP Top 25 is the highest the Irish have been since Brian Kelly took over the team in 2010. It is also Notre Dame's highest ranking in the AP poll since it was No. 11 in Week 15 of the 2006 season.
Michigan State (2-1) went from No. 10 in the AP poll to No. 21, and the Spartans fell to No. 20 in the coaches' poll after being No. 10 last week.
Notre Dame's road doesn't get any easier this week as the Irish play host to Michigan (2-1), which is ranked 18th in the AP poll and 17th in the coaches' poll.
Irish linebacker Manti Te'o was also named the Walter Camp national defensive player of the week for his performance against the Spartans.
Te'o, whose grandmother and girlfriend died in the days leading up to Saturday night's game, had 12 tackles, broke up two passes and recovered a fumble against Michigan State.
