You may remember seeing a fight video in the last couple of days between some LSU tailgaters. It was posted on this website Sunday evening.

It involved one man being knocked out (or at least it looked that way) by another man wearing a purple plaster arm cast.

Police are reportedly now investigating that incident after the video went viral on Sunday, according to Baton Rouge ABC affiliate WBRZ.

The fight apparently occurred on the LSU Parade Ground during a tailgate before Saturday’s LSU-Chattanooga game.

LSU’s Police Department reportedly confirmed to WBRZ that it is investigating the incident, and more information is expected after police complete the investigation.
