LINCOLN, Neb. -- Michigan football was alone in history as the only program with 500 Big Ten wins ... for a few hours.

The Wolverines reached the mark on Saturday afternoon with a 27-20 overtime win at Indiana. Ohio State joined them on Saturday night with a 56-14 win at Nebraska.

Two programs linked through bitter rivalry became the first to reach 500 Big Ten wins on the same day. That weird connection comes with a twist.

Ohio State could have been the first program to reach 500 Big Ten wins, and would have accomplished that feat last year were it not for the seven vacated conference wins from the 2010 season. Those don't count in the official tally. So Michigan got first honors, and stood alone for an afternoon.

Michigan, an original Big Ten member school, is 500-203-18 all-time, having played in the conference since 1896.

Ohio State is 500-173-24 since it began Big Ten play in 1913.

The Buckeyes also moved into a tie with Nebraska for fourth in NCAA history with 892 program wins. Michigan leads with 940.
