The announcement was made in Washington’s Husky Stadium and the sellout crowd at the Washington-USC game roared. Pittsburgh 43, Clemson 42. It is safe to say that never before has an ACC score made a Seattle crowd so excited.
Then Washington went out and lost, too. And Michigan followed up with a loss at Iowa and just like that there were three College Football Playoff-shaking results on a Saturday when all the top contenders were big favorites.
Chris Blewitt made a 48-yard field goal with six seconds left as Pittsburgh stunned No. 3 Clemson 
43-42, spoiling a record-setting Saturday for quarterback Deshaun Watson and complicating the Tigers’ path back to the College Football Playoff.
It was the biggest win for the Panthers (6-4, 3-3 Atlantic Coast Conference) since knocking off No. 2 West Virginia 13-9 in 2007.
Freshman Keith Duncan kicked a 33-yard field goal as time expired and Iowa stunned second-ranked Michigan 14-13 on Saturday night, damaging the Wolverines’ playoff hopes.
Akrum Wadley had 115 yards rushing for the Hawkeyes (6-4, 4-3 Big Ten), who beat a top-five team for the first time in six years.
Michigan (9-1, 6-1, No. 3 CFP) appeared to have the game wrapped up on Channing Stribling’s interception of Iowa quarterback C.J. Beathard with 1:54 left. But the Hawkeyes defense stuffed the Wolverines, and a facemask penalty put Iowa at Michigan’s 36 with 1:23 to go.
Sam Darnold threw for 287 yards and two touchdowns and USC upset No. 4 Washington 26-13 on Saturday night, snapping the Huskies’ 12-game winning streak and damaging their College Football Playoff hopes.
We all await the shake up of the college playoff rankings after these three stunning losses. Louisville (Defeated Wake Forest 44-12) and Ohio State (dominated Maryland 62-3) are sure to move up after 3 of the top 4 in the college football playoff rankings lost this week.
Here are the top 10 from the AP’s Top 25 College Football rankings:
