Florida State and Clemson will not play Saturday after the team's medical personnel could not mutually agree on moving forward with the game, the ACC said in a statement.
The teams were supposed to play at noon in Tallahassee.
"We are disappointed that we will not be able to play today's game against Florida State," tweeted Clemson AD Dan Radakovich. "Clemson has followed all of the ACC's protocol in preparation for this game. We look ahead to returning to action next week against Pitt for Senior Day and Military Appreciation Day."
In a statement, the league said both teams continue to adhere to the minimum outlined protocols within the ACC Medical Advisory Group report.
