Michigan and Notre Dame will play their annual football game through 2031.

The schools were scheduled to meet each season through 2011, but they agreed today to a 20-year contract extension.

The schools are one and two in wins and winning percentage in college football history. Michigan is 860-282-36 with a .745 winning percentage. Notre Dame is 821-269-42 with a .744 winning percentage.

Michigan leads the all-time series with a 19-14-1 record.

The rivalry dates back to 1877, when some Michigan students taught the game to Notre Dame students. They stopped playing after the Irish earned their first victory in 1909 after eight straight losses.

The schools played again in 1942 and 1943, splitting the games, before resuming the series in 1978.
