According to the 32 Thoughts Podcast, Walman's celebration didn't sit well with some in the NHL, who believe there may be retaliation when the two teams meet again later this week. However, it seems the league has issued warnings to both teams regarding potential retaliation.
Given that the Rielly incident, stemming from Ridly Greig breaking the code, occurred on Friday, it's expected that both teams will receive warnings before their upcoming game.
