There was blood before the game ... and fires afterward -- but the Philadelphia PD tells us only 6 PEOPLE were arrested on Sunday in connection to the NFC Championship madness.
One person was arrested for assault on a police officer -- we're told the incident took place in the parking lot at Lincoln Financial Field before the game.
2 more people were arrested for disorderly conduct -- and 3 others were busted for counterfeit ticket sales.
All in all ... seems like a win considering the videos and photos that surfaced showing police on horseback taking control during the pregame tailgates.
Afterward, fans went crazy in the streets -- but according to police, it wasn't as bad as social media made it look.
