The Cleveland Browns were on the short end of one of the strangest replay reviews in recent NFL history.
After running back Carlos Hyde appeared to achieve what would like have been a game-clinching first down with 1:32 left on the clock, the on-field call was reversed by the replay official, who called for a review of the play.
The call was overturned, Browns National howled in disbelief - as did many non-Browns fans - and the Browns would eventually go on to lose the game in overtime.
On Monday, the NFL came up with an explanation for why it overturned a play that did not seem to have enough evidence to change the on-field call of a first down.
