The Buckeyes are no strangers to facing service academies, having gone against Navy in both 2009 and 2014 -- and in the process discovering the challenges and pitfalls of facing a triple-option team and the blocking practices they employ (particularly in a season opener).
Though OSU and Navy aren't set to meet again, having completed both legs of that home-and-home, Ohio State will take on the United States Military Academy on Sept. 16, 2017. ESPN's Brett McMurphy first reported the news. It was reportedly previously the two sides were talking about potential future matchups.
The Buckeyes will open the season in conference play at Memorial Stadium two weeks earlier that year, with the Indiana Hoosiers hosting the Buckeyes. OSU returns home a week later to play host to Oklahoma in what should be a much ballyhooed out-of-conference matchup. The Sooners also moved their date with Ohio State up a week to September 9, so the Buckeyes will face Oklahoma, Army and UNLV in consecutive weeks after their season opening trip to Indiana.
In other scheduling news, the Buckeyes also announced they will host Florida Atlantic on August 31, 2019. The Owls boast an Ohio State connection, with former Buckeye Pat Chun currently serving as their athletic director. The two schools also joined together for a satellite camp earlier this summer, so perhaps working together for a football game was inevitable. That will serve as Ohio State's season opener. The Buckeyes are also currently scheduled to host Cincinnati and TCU in 2019.
Barring future schedule adjustments, Ohio State's out of conference schedules are now booked through 2017, with one opening remaining in 2018. Given that Ohio State faces two Power Five teams that season (Oregon State, at TCU), expect the third team to of similar caliber to FAU or Army.
