LeBron misses dramatic ending to Cowboys-Lions game

LeBron James is a die-hard Dallas Cowboys fan, but he missed the end of their dramatic loss to the Lions.

Remember Game 6 of the NBA Finals last season?

The one where hundreds of Miami Heat fans filed out of Americans Airlines Arena early, only to miss Ray Allen hitting a game-tying three-pointer at the end of the game that led to the Heat winning in dramatic fashion in overtime as those same fans tried, and failed, to reenter the building?

Well, it seems one Miami player ... and mega Dallas Cowboys fan ... did not learn his lesson from that game.

LeBron James spent most of the day live-tweeting during the Cowboys game against the Detroit Lions, gloating with glee as his Cowboys seemed like they had a victory wrapped up with a minute left to play.

One bathroom break and Matthew Stafford game-winning drive later, and the King was left wondering what the heck happened.

LeBron ... never leave an NBA Finals game early ... and never assume the Cowboys have a game wrapped up, no matter how bad you have to go to the bathroom.
