Hi, Could you help me, please, with understanding some sport routine.

This is the context:" Now, 3-0, Canada will practice today to face an American squad on New Year’s Eve in the final game of the round-robin portion. First place in Group A – and a bye through the quarter-finals-will be on the line."

Thank you.
I'm not a sports fan, but I'm pretty sure a "bye" means you don't have to play. I think the reasoning is that the team presumed to be in the lead sits by while the lesser teams eliminate somebody, and then plays the winner. It gives the players a valuable rest period, too.
"Bye" is also used metaphorically in non-sports-related situations. Father, to teenager who has come home at one o'clock in the morning: "You get a bye this time, son, because we weren't clear about what time we expected you home. But don't let it happen again."

Delmobile, thank you. With the father and son this would be, like, father says " I'll let you go this time", right?
Yes, or "I'll let it go this time," "it" being the infraction.
