Buffalo Bills running back LeSean McCoy was involved in an altercation with three off-duty police officers this past weekend in Philadelphia, according to multiple reports.

“We are aware of the reports regarding LeSean McCoy and in the process of gathering more information,” a statement from the Bills read. “We will not provide any further comment at this time.”

McCoy, along with former NFL running back Curtis Brinkley, had “a dispute over the purchase of champagne” which touched off the altercation at an Old City nightclub, according to reports.

According to reports, officers Darnell Jessie, Roland Butler and Sergeant Daniel Ayers purchased four bottles of champagne that evening. Former Pitt football player Tamarcus Porter tried to take one of the bottles from Butler and “an argument ensued as to the ownership of the bottle,” at which point McCoy, Brinkley and Christopher Henderson “assisted [Porter].”

Recess, the nightclub where the fight took place, had surveillance cameras, but they were not working, according to the reports.

It’s unknown whether either McCoy or Brinkley was injured. One of the officers suffered a possible skull fracture and another was treated for a broken nose, broken rib, an eye laceration and a sprained thumb, per the reports.

McCoy played six seasons with the Philadelphia Eagles before getting traded to the Bills last offseason.
