A fan at the Anaheim Ducks game on Friday night appeared to be knocked completely unconscious during a wild brawl … and now, cops say they’ve launched an investigation into the matter.
The fight broke out as the Ducks took on the Winnipeg Jets at the Honda Center … when a group of fans who were reppin’ opposite teams got into it with each other right in the middle of a concourse.
You can see in video from the scene … a man in a Jacob Trouba Jets jersey broke off from the squabble and began tussling with a guy in purple Ducks jersey.
During their ensuing wrestling match, the Winnipeg fan slammed the Anaheim supporter to the tile floor using a leg takedown maneuver … appearing to leave the man KO’ed.
The guy lay motionless for several moments … before he rolled over in what seemed to be a heap of pain.
The Anaheim Police Dept. said in a statement to TMZ Sports officers were dispatched to the area after the tilt had gone down … and one person was transported to the hospital with a head injury.
“The investigation is ongoing,” a spokesperson for the department said, “and no arrests have been made.”
Cops added they will be using “videos circulating on social media” “as a part of our investigation.”
