What happened: The Canadian anthem was sung first before Buffalo's first regular-season game at the new Highmark. The Bills had already announced they would add O Canada alongside the U.S. anthem for the home opener.

Why it matters: The sequence turned a pregame ceremony into part of the night's early conversation before kickoff. It also put extra attention on a stadium-opening presentation choice while the scoreboard was still 0-0.

What to watch: Watch whether Buffalo keeps the same anthem order for future home dates or limits it to the opener.
