"The guy goes up and does it, and then runs away," Nodiff said.
That's where the video picks up.
Wearing a No. 24 Ryan Callahan Rangers jersey, Auricchio stands surrounded by Flyers fans. He puts his hands out, as if trying to play peacemaker.
A man who looks to have about a one-foot height advantage on Auricchio removes his dark coat with white fur trim, uncovering his No. 28 Claude Giroux Flyers jersey.
He shoves Auricchio, who still has his hands out, and then throws a punch.
Auricchio throws back, punching up, but is quickly overwhelmed when a man in a No. 68 Jaromir Jagr jersey begins punching him, too. The two hit Auricchio about a dozen times as he lies on the ground.
When a Flyers fan tries to pull them off Auricchio, the man with No. 28 and two other men begin to beat another Rangers fan.
When Auricchio stumbles to that man's aid, No. 28 blindsides him with a punch, knocking him to the ground unconscious.
Some people yell, "Enough! Enough!" and, "Easy!" Someone else yells, "Go to sleep!"
No. 68 then kicks Auricchio. No. 28 steps over him and picks up his fur-trimmed coat.
Auricchio was treated at a New Jersey hospital for a concussion, said Woodbridge Mayor John McCormac, a longtime family friend. Auricchio has a stitched-up cut under one eye, and the other eye is still swollen nearly shut.
"He's still in a lot of pain," McCormac said. "He's starting to see out of the one eye, but we're waiting for the results of the CAT scan, hoping there's no damage we don't know about it."
Auricchio is married and welcomed his first child, Vincenzo, the week before Christmas.
He was shot by a sniper in Fallujah during his first tour in Iraq. He went back in 2007, the day after graduating from the Woodbridge Police Academy.
