SOUTH BEND, Ind. — Kyren Williams had a 3‑yard touch­down run in the sec­ond over­time and No. 4 Notre Dame shut down top-ranked Clem­son with a cou­ple of sacks to seal a 47–40 vic­to­ry Sat­ur­day night, the Fight­ing Irish’s first vic­to­ry over a No. 1 in 27 years.

Clem­son (7–1, 6–1) had won 36 straight games and had not lost to an Atlantic Coast Con­fer­ence team since 2017. The Fight­ing Irish (7–0, 6–0), play­ing in the ACC only because of the pan­dem­ic, snapped both streaks and sparked fans to storm the field in a cel­e­bra­tion that most def­i­nite­ly did not meet the CDC’s social-dis­tanc­ing guidelines.

After Williams gave Norte Dame the lead on the first pos­ses­sion of the sec­ond OT, the Irish pushed Clem­son back with back-to-back sacks on DJ Uaigalelei by Adetokum­bo Ogun­de­ji and Daelin Hayes on the first two plays.

The big fresh­man quar­ter­back com­plet­ed to pass­es after the sec­ond-and-39, but the final one was way short of the line to gain and a cou­ple of lat­er­als didn’t help.

The Fight­ing Irish have won 13 straight games, snapped an 11-game los­ing streak against top-five teams and beat a No. 1 for the first time since tak­ing down Flori­da State in 1993 at Notre Dame Stadium.

Uia­galelei, start­ing in place for Trevor Lawrence for a sec­ond straight week, passed for 439 yards, the most ever by an Notre Dame oppo­nent. Lawrence was on the side­line for this one, a few days out of iso­la­tion after hav­ing COVID-19.

The biggest game at Notre Dame Sta­di­um since No. 1 South­ern Cal­i­for­nia beat the Irish with the Push Bush in 2005 had only 11,011 in atten­dance, most­ly stu­dents, because of pan­dem­ic restrictions.

When it was over, they poured onto the field to cel­e­brate with their team. Notre Dame coach Bri­an Kel­ly retreat­ed to the tun­nel to avoid the crowd.

“I want to be able to coach next week,” Kel­ly told NBC.

The Fight­ing Irish need­ed a two-week break ear­li­er this sea­son because of a COVID-19 out­break, but it didn’t keep them from enter­ing this show­down with Clem­son unbeaten

They might just see each oth­er again in the ACC cham­pi­onship game in December.
