The Dallas Cowboys lost to the New York Giants, but they aren't exactly willing to call it a fair fight.

At certain points in the Week 14 contest, Giants head coach Ben McAdoo was seen holding and communicating with a walkie-talkie on the sideline. After the game, Dallas Fort-Worth radio station 105.3 The Fan reported that the Cowboys were going to formally request the NFL to investigate the matter.

At some point during the contest, Giants quarterback Eli Manning lost communication in his helmet earpiece. That led to wide receiver Odell Beckham Jr. turning into a makeshift "Pony Express" as he ran back and forth between McAdoo and Manning to get offensive plays in.

A replacement helmet required McAdoo to use a handheld two-way radio to speak with the quarterback from the sidelines.

In the end, McAdoo was seen using the walkie-talkie which could possibly violate NFL rules as the form of communication is not regulated by the league itself.

There is some cause for concern on the Cowboys side with Beckham running in plays while the Giants were still using the walkie-talkie to communicate. Who exactly was McAdoo talking to?

The Cowboys simply want some clarity.

The in-helmet microphones are cut by an NFL employee when the play clock hits 15 seconds, but no such action could have occurred with McAdoo using the handset — potentially creating an unfair advantage.

It may never be known if this gave the Giants just enough leverage to win a nail biter against the Cowboys, but Dallas wants the NFL to do something about it.
