In the second quarter of the Redskins' preseason matchup vs. the Bengals, Case Keenum found Steven Sims for what looked like a massive gain and possible touchdown. However, Cam Sims was called for offensive pass interference, which erased the highlight.

That's when things got wacky.

Jay Gruden threw his challenge flag, looking to take advantage of the NFL's new rule that coaches can trigger a review of interference flags. Here's the play, in which you can see Cam bump a defender while crossing the field, a slight collision that helped free up Steven: 

The refs went under the hood and deliberated for a good chunk of time, but ultimately, the decision on the field was upheld. So, Gruden is now 0-1 when it comes to challenging penalties, and everyone else is still getting used to this bizarre new football world we're living in.
