Notre Dame originally reached 900 wins in 2017 while appealing an NCAA mandate that the school vacate 21 victories because of academic misconduct, including all 12 wins from the school's 2012 run to the national championship game, as well as nine from 2013.
The NCAA denied the school's appeal in February 2018, putting its official win total back under 900. The university's president, the Rev. John Jenkins, strongly criticized the NCAA's decision at the time, saying the school was being punished for rigorously enforcing its honor code.
The decision ultimately allowed the No. 6 Sooners to beat Notre Dame in the race to an official 900 by a matter of hours on Saturday, running away from Texas Tech 55-16 before the No. 10 Irish matched them with a 35-20 win over No. 18 Virginia.
The schools join Michigan (956), Ohio State (916), Texas (911), Alabama (910) and Nebraska (900) as the only Football Bowl Subdivision programs to achieve 900 wins. The Cornhuskers won No. 900 last weekend by beating Illinois. Yale, now in the Football Championship Subdivision, has 909 wins.
Both Oklahoma and Notre Dame have 325 losses to go with their 900 victories. The Sooners have played in 11 more ties than the Irish, 53-42.
Oklahoma is in its 125th season of football, posting the fifth-best winning percentage nationally though its first 124, with only 13 losing seasons. The Sooners own seven national championships.
Notre Dame, which started playing in 1887, has 11 national championships dating back to 1924, with the most recent coming in 1988. Entering the game against Virginia, Notre Dame had an all-time win percentage at 72.7.
