While the crowd at Arrowhead Stadium erupted in joy, Jim Nantz on the CBS broadcast quickly said there was a flag on the play, giving Bills fans a little bit hope during a very dark moment. But then talk of the flag quickly went away as refs apparently didn't throw one and no penalty was called.

For a brief second after Josh Allen's desperate fourth down heave hit the turf at Arrowhead Stadium, the Buffalo Bills had hope. "There is a flag,” CBS play-by-play standby Jim Nantz announced to the masses watching at home.

Tight end Dalton Kincaid was able to track down the ball but could not haul it in, turning the ball over to the Chiefs who ran out the clock and secured the 32-29 victory. There was a bit of mystery on the play, however, with CBS announcer Jim Nantz saying officials had thrown a flag -- a call that was never explained during the broadcast.

Interestingly enough, Kevin Harlan and Devin McCourty, calling the game for Westwood One Radio, also said there was a flag on the play, with McCourty speculating that it was for Bills offensive lineman Dion Dawkins taking his helmet off.
