COVID-19 outbreaks have disrupted over 100 games across college football in the last few weeks.

Most recently, it has been reported by the Associated Press that the Michigan Wolverines have had at least 12 positive cases within their program, and the impact of the news has a potential impact on the College Football Playoffs.

While the size of the outbreak has not been officially disclosed by the school, sources told the Associated Press on Thursday that the number of players, coaches and staff members who were among the positive cases wasn’t known, nor how many were under quarantine due to contact tracing protocols.

Michigan has already canceled this weekend’s scheduled game against Maryland, and the outbreak now puts in question next week’s rivalry game with No. 3 Ohio State.

The Buckeyes have missed two games already due to cancellations, and another would leave OSU unable to reach the B1G mandated minimum games to be eligible for the Big Ten Championship game, further putting in jeopardy a potential CFP berth.

Wolverines head coach Jim Harbaugh said team meetings would be conducted virtually after the number of tests increased, and like Ohio State, the cancellation of the Maryland game resulted in their second game of the season scrapped due to COVID-19.
