"They're getting our signals," Snyder told ESPN sideline reporter Samantha Ponder, adding that the Wildcats changed up some of their signals during halftime.
Auburn coach Gus Malzahn denied any first-half advantage after the game, which the Tigers won 20-14.
"No, no," he said when asked if Auburn knew the signals.
Florida State coach Jimbo Fisher made the same claims against Auburn after January's BCS National Championship Game win, as the Seminoles reportedly used towels to block some of their signals.
