Buffalo Bills running back LeSean McCoy is being investigated for an incident that allegedly took place early Sunday morning at the Recess nightclub in Philadelphia.

A report from CSN Philly cites that former NFL player Curtis Brinkley, former Pitt football player Tamarcus Porter and Christopher Henderson were at Recess around 2:45 a.m. ET, when an altercation broke out over a bottle of champagne. Three off-duty Philadelphia police officers—Darnell Jessie, Roland Butler, and Sgt. Daniel Ayers—were involved as well, and Butler and Porter reportedly got into it. McCoy, Brinkley and Henderson then “assisted” Porter by punching, kicking, and stomping on Butler multiple times.

The website CrossingBroad.com was able to attain video of the incident, and they’ve since released it to the public.

The report from CSN Philly cites that two officers suffered broken ribs, one of whom may have also suffered a skull fracture.

This doesn’t look good for McCoy. It’s hard to see whether or not it was him for sure in the video, and his agent refused to comment on the situation, but it looks like he was involved, at least in some form.
