Clemson displaces Ohio State as the No. 1 team in the Associated Press poll.

Clemson is the new No. 1 team in the Associated Press college football poll, knocking Ohio State from the top spot for the first time this season.

The Tigers, who were ranked No. 1 in the first College Football Playoff poll last week, are topranked in the AP media poll for the first time since the final poll of the 1981 season, when Clemson won its only AP national title.

The Tigers (9-0) received 31 first-place votes and 1,489 points after beating Florida State 23-13 on Saturday. Ohio State (9-0) had 26 first-place votes and 1,460 points. The defending national champions had been first since the preseason.

Third-ranked Alabama (8-1) climbed four spots and got two first place votes, and No. 4 Baylor also received two firstplace votes.

Houston moved up to 16th.

Big Ten: Officials got call right

The Big Ten said Sunday that officials used the proper mechanics to indicate a Nebraska player stepped out of bounds and returned to the field before catching the winning touchdown pass against Michigan State on Saturday night.

The conference, however, didn’t say whether the officials’ determination that Brandon Reilly was forced out of bounds — and thus able to come back inbounds and make a legal catch — was right.

“We don’t comment on judgment calls but can confirm that proper technique was used, and provide additional information on instant replay,” conference spokesman Scott Chipman wrote in an email to the Associated Press.

The Spartans’ 39-38 loss all but ended their hopes of making the College Football Playoff. They dropped from No. 6 to No. 14 in this week’s AP poll. They were No. 7 in last week’s initial CFP top 25.

Michigan State was trying to hold off a late charge by Nebraska when the Cornhuskers’ Reilly stepped out of bounds at about the 7 and came back in to catch the 30yard pass from Tommy Armstrong Jr. with 17 seconds left. After huddling, officials ruled Reilly was forced out of bounds by cornerback Jermaine Edmondson — allowing Reilly to remain an eligible receiver. Though there was slight contact between the two, television replays did not support that Reilly was pushed or forced out.

Referee John O’Neill announced the play would be reviewed. But the only thing replay official Tom Kissinger could review under the rules in this circumstance was whether Reilly stepped out of bounds or if there was contact. The answer to both was yes.

Pac-12 suspends official for error

The Pac-12 suspended line judge Rich Troyer for one game and downgraded the entire officiating crew for giving Washington State an extra down in its game against Arizona State on Saturday.

The play came in the second quarter, when Washington State receiver Gabe Marks appeared to be stopped short on a fourth-down attempt as a whistle blew the play dead by the officials. After huddling, the officials determined it to be an inadvertent whistle and gave the Cougars another play.

Washington State scored on the next play and went on to win 38-24.

Prosise suffers concussion

Coach Brian Kelly said running back C.J. Prosise is undergoing concussion protocol after being injured in No. 6 Notre Dame’s win over Pittsburgh.

He will go through a physical conditioning test Monday, and Kelly is hopeful Prosise will be able to play against Wake Forest.

Prosise leads Notre Dame (8-1) with 975 yards rushing on 148 carries, an average of 6.6 yards.
