It's safe to say that the Houston Texans' Bill O'Brien reached his breaking point during the team's Week 14 loss.

For those that can't recall, the Texans were blown out by the lowly Denver Broncos by a score of 38-24. The game's final score was much closer than the actual game, however. Denver blew out Houston from the onset, taking a 31-3 lead at halftime before coasting for the remainder of the game.

Keep in mind that this was just a week after the Texans had pulled off a major victory over the New England Patriots on national TV. Needless to say, emotions boiled over as one particular fan got to the Texans head coach. Check out this profanity-laced tirade from O'Brien directed at this particular fan at NRG Stadium at the game back in Week 14, via TMZ Sports.

“Screw you, motherf**ker! You suck, too! Hey! You suck too, motherf**ker!!!”

Star wide receiver DeAndre Hopkins even tried to intervene to calm his head coach down — but there was no stopping O'Brien, as he continued to lay it on the fan.

It's safe to say that with the Texans preparing to face the Kansas City Chiefs in the Divisional Round of the playoffs, O'Brien is probably in better spirits.

However, this obviously isn't a good look for O'Brien or the NFL — a league that prides itself on professionalism.
