No. 12 Miami had its remaining three games postponed Monday because of COVID-19 cases in the program, forcing the Atlantic Coast Conference to reschedule a total of six games over the last month of the season.

Georgia Tech at Miami scheduled for Saturday is now tentatively set for Dec. 19, the date of the ACC championship game. Miami’s game at Wake Forest that was scheduled for Nov. 28 was moved to Dec. 5, and its game against North Carolina was moved back a week to Dec. 12.

“What we know is we don’t have a coronavirus-in-college-football problem. We have a coronavirus-in-America problem,” Miami coach Manny Diaz said Monday. “And everyone, I hope, can see or I would hope can see — you can’t say everyone can see, because the way things are in 2020 everybody can’t agree on anything — but certainly the math is saying that the numbers are really, really getting to a bad place.”

Georgia Tech, which had its game last week against Pittsburgh postponed because of COVID-19 issues with both teams, joins No. 5 Texas A&M and Arizona State as teams that will now go two weeks without playing.

The number of games across major college football scheduled for this weekend that have already been called off is up to six, after three went down Monday, including Mississippi at Texas A&M.

Texas A&M coach Jimbo Fisher said the program had only one active case but the number of players available to practice was “in the 40s,” about half of what it would usually be. Most of the absences were due to individuals being quarantined after being exposed to someone who tested positive for the virus.

The Aggies missed last weekend’s visit to Tennessee.

“We were wondering if we’d even have football. So we can complain about this and this and that but, listen, we’re still getting to play football,” Fisher said. “The season’s going on. So those are great things for us and the SEC and everybody in college football.”

The Southeastern Conference, which has had eight games postponed this season, said the Texas A&M-Ole Miss game could be made up Dec. 19, the day of the league championship game and a week after the Aggies play the make-up against the Volunteers.

The ACC moved up the Wake Forest at Louisville from Dec. 5 to Nov. 28.
