Watch: Livid Lions HC Dan Campbell sounds off following controversial penalty on two-point play

The Detroit Lions were on the losing end of a 20-19 decision to the Dallas Cowboys on Saturday night thanks to a controversial penalty on a two-point attempt that would have won the game. 

Lions head coach Dan Campbell was extremely emotional after the game and could barely discuss what happened without getting more and more angry. 

The Lions had a play drawn up that saw quarterback Jared Goff complete a pass to offensive tackle Taylor Decker that appeared to give the Lions a 21-20 lead with only 27 seconds to play in regulation.

But a late flag was thrown and the Lions were called for an illegal touching as Decker was called for not reporting as an eligible receiver on the play. Detroit ended up still going for two — including after a Dallas offside penalty on the second attempt — and did not score. 

Referee Brad Allen had announced prior to the original play that No. 70 Dan Skipper was the one that reported as eligible, and not Decker. 

Replays, however, clearly showed Decker walk up to Allen before the huddle. He would not be doing unless he was reporting as eligible. Both Decker and Skipper, as well as quarterback Jared Goff, said after the game that it was Decker that had reported.

Campbell was also adamant that it was Decker that reported during an emotional press conference where he was visibly livid.
