"What I'm going to tell you is that if you're a big boy or a big girl, and you write - Mason Scary Collision - on Twitter, you'll find out why he's not there (Martin St-Louis). [...]
There is a public part to the reason for Martin St-Louis's absence."
Indeed, when entering "Mason scary collision" on X, the full explanation is there, in plain sight:
"Hard fought 7-3 win vs SPA. Hard to be happy as our friend and teammate Mason left the game in the 3rd after a scary collision. Good news is he's going to be okay but it takes an emotional toll. Have to do our best to re-focus and get ready for a battle tomorrow vs MSC at 8am."
