Love 'em or hate 'em, the Dallas Cowboys are one of the most talked about NFL teams in the country. After all, they are "America's Team."
The Jacksonville Jaguars? Not so much. They are actually the least popular team in the country, according to Facebook.
With that in mind, it makes sense to send both teams to London for a game as the NFL looks to build its popularity overseas.
But despite who wins the actual game on Sunday, it looks like the Cowboys have already shot themselves in the foot in a major way.
Promoting the big London game on Twitter the Cowboys used the hashtag #CowboysUK, which looks a lot more like "Cowboys suck" rather than promoting the Cowboys in the UK.
And, as you can probably guess, the Internet had a field day with the misguided hashtag.
The players even got in on the action:
Here are some of the outrageous reactions on Twitter:
In response, it looks like the Cowboys have changed their hashtag for now.
Meanwhile, Jacksonville seems to have put in more thought to their hashtag. They went with #JAXinUk.
And, when the Cowboys posted this, I can only imagine that more trouble is headed their way. I envision it going like this Twitter chat gone awry with NFL commissioner Roger Goodell.
