"I'm not really worried much about what they say down there in Tallahassee," Swinney said, according to The Athletic's Grace Raynor. "I've been in this league 18 years, I've been the head coach for 12. They've had three head coaches in four years."
Swinney initially said the Seminoles were using a positive test on the Tigers as an "excuse" to back out of their Nov. 21 matchup hours before kickoff. The two-time national champion added that Florida State should have been forced to forfeit the game.
Florida State's Mike Norvell defended his program a day later, dismissing Swinney's opinion that it was safe to play.
"Football coaches are not doctors," Norvell said. "Some of us might think that we are, but there's a reason why those advisors are able to make the decisions from the information that is provided."
Swinney shared his frustration with that response during his radio show.
"The last thing we would ever do is put somebody in harm's way," he said Monday night, according to Matt Connolly of The State. "And it's an insult to the credibility of our program, the credibility of our medical people. And we all agreed to the same rules, and just magically those rules changed on Saturday morning."
He added: "We had no positives yesterday. Zero. We tested yesterday, zero. We had 150 tests Friday, one positive. And we didn't travel anybody with (symptoms). Are you kidding me? This was a backup offensive lineman that wasn't even going to probably play."
Clemson has won its past five meetings with Florida State. The Tigers are looking to book a spot in the College Football Playoff for the sixth straight year.
