A Tampa Bay Lightning fan appeared to have been knocked unconscious after being sucker-punched by a New York Rangers fan while leaving Thursday's game at Madison Square Garden.
Video of the incident, which was captured by a fan and posted on social media, shows the attacker turning around and punching the victim across the face as fans were exiting the arena following the Rangers' 3-1 loss to the Lightning in Game 5 of the Eastern Conference Finals.
The victim fell to the floor of the exit ramp and laid motionless while being tended to by fans.
As the attacker fled, fans yelled for security.
James Anastasio, 29, of Staten Island, was arrested and charged with two counts of assault, two counts of disorderly conduct, and two counts of harassment.
The victim refused medical attention. Social media erupted the following day, especially on Twitter. Many people showed their ill support of the one-sided brawl, some even saying they feel sorry for the Rangers organization.
Rangers fans do not approve of this behavior.
