The Tennessee Titans and Baltimore Ravens have some history as AFC heavyweights in recent years.

But before their game on Sunday, Malcolm Butler of the Titans and Ravens coach John Harbaugh got into a nose-to-nose back-and-forth on the Ravens logo. It was unclear what sparked the original brouhaha other than the Titans coming out and immediately going to the logo.

This is the kind of thing to monitor as the game goes on to see if there are any personal foul penalties.

Here’s a recap of what went down, including some video of the incident:
