Fisher appeared to hook Steelers pass rusher James Harrison on the conversion attempt with less than 3 minutes left in the game. But the play was not cut-and-dried: Harrison dipped especially low and may have been losing his balance, and he likely would not have gotten to the quarterback anyway.

Still, the flag negated the successful 2-point conversion. And when the Chiefs tried again from the 12-yard line, Alex Smith’s throw fell incomplete and the Steelers were able to run out the clock.
