A news release stated that there is not enough evidence to meet the "legal threshold" to issue charges.
Philadelphia District Attorney R. Seth Williams said in February that his department was still reviewing evidence tied to the alleged altercation at a Philadelphia nightclub on Feb. 7. McCoy met with Williams later in the month, according to NFL Media's Albert Breer.
McCoy was one of four suspects under investigation for allegedly assaulting the off-duty officers, according to the Philadelphia Police Department. One of the off-duty officers was knocked to the ground and "punched, kicked and stomped about his body and head multiple times," according to a Philadelphia police news release obtained by NFL Media in February.
Each of the officers suffered broken ribs. In addition, police said the officers suffered other injuries, including a lacerated eye, broken nose, broken ribs and a sprained thumb.
