From the Stranger than Fiction Department:
--Trey Sermon scored a touchdown today against MSU for OSU.
--His 2nd touchdown when OSU is on the field.

The other was September 29th, 2017 as a Sooner.
--This makes him the SECOND player to score for and against OSU.
--While Sermon's 'for and against' were 1183 days apart, the record is 0.

Yes, it happened in the same day on October 22, 1898.  The HB: Bob Hager.

Marietta was ahead 3-0 in the second half when one of their players was injured. In the early days of college football, teams rarely traveled with more than a few backup players, and in this game, Marietta only had one backup, and that player has already been called into the game because of a prior injury to a different Marietta player.

So now down to 10 players, Marietta was faced with having to forfeit the game. With no other option, the coach of Marietta asked Ryder if Ohio State could loan them a player to finish the game. Ryder agreed, and halfback Bob Hager switched teams.

That switch would prove to be quite problematic for Ohio State, as Hager would score on a 67-yard touchdown run later in the game, providing the final scoring in a 10-0 Marietta victory.

Ryder was fired at the end of the season.

I guess lending a star player to the other team at the half angered the whatever form boosters took back in 1898.

Anyway, it's been over 122 years since it last happened... Congrats to both Sermon and the descendants of Bob Hager.
