Who is Singing the National Anthem at Bills-Chiefs AFC Title Game?

Just last weekend the Buffalo Bills punched their ticket to the AFC title game with a 27-25 victory over the Baltimore Ravens.

Following the win, head coach Sean McDermott had a message for the team's doubters as they prepare for a bout against the Kanas City Chiefs with a spot in the Super Bowl on the line.

"Our guys heard it all -- they heard it all week long. We're not big enough, we're not strong enough. Not talented enough. Whatever it is, they heard it," McDermott told reporters this week. "I don't do the social media things, but I think most of those guys do. And look, we did, I think, in the first half a pretty darn good job. Second half, [Henry] got rolling a little bit. And he's going to pop some runs, I mean, when he gets that momentum, he's hard to stop. So, but even there, we could have done some things better, and I think fundamentally, so when we just look at this game, it came down to fundamentalism in football. And we talked a lot about that."
