The Nashville Predators tweeted out a message from Head Coach Peter Laviolette to warn fans against throwing anything on the ice so the team doesn't get penalized.
They throw catfish on the ice in Nashville, it happened probably around 5 times over the span of Game 3. There was also a rally towel dropped/thrown at Penguins players when they were leaving the ice after Game 3.
