Buffalo Bills running back LeSean McCoy has denied any involvement in disturbing claims against him made on social media.

A friend of Delicia Cordon, who has been in a relationship with McCoy in the past, has accused McCoy of some heinous actions — most notably domestic violence — on her Instagram post from Tuesday morning.

The graphic post shows pictures of Cordon, before and after she had a badly beaten face, claiming that McCoy was the one who was responsible. In addition, the friend — with the username “miamor_i_adore” — accused McCoy of beating his dog into kidney failure, drug use (“illegal steroids and needles”) and having to be held back by others from abusing his son.

It reads, in part: “…we will not keep quiet about this!!!!!! I can’t believe you did this to my best friend!!!!! YOUR KARMA IS GOING TO BE SO REAL!!!!!! The world needs to know what type of animal you really are!!!!!!! This was just her yesterday on the left and now this morning this is her on the right!!!!”

The alleged attack occured at a house in Milton, Ga. — it's believed to be owned by McCoy and where Cordon was staying — after an intruder broke into the residence. Milton Police issued a statement about responding to a call at the home: "On July 10, 2018 at approximately 3:18 A.M., Milton Police responded to a home invasion at a residence on Hickory Pass near the Cherokee County line. The preliminary investigation indicates that this residence was specifically targeted by the suspect or suspects, and not a random incident. When officers arrived they found one victim who had been physically assaulted by a lone intruder. During the altercation, the suspect demanded specific items from the victim. An adult female victim was treated and released at North Fulton Regional Hospital. A second adult female victim also sustained a minor injury during the incident."

McCoy defended himself on Instagram and denied any responsibility, saying: "For the record, the totally baseless and offensive claims made against me today on social media are completely false" and that he has "not had any direct contact with any of the people involved for months."

PFW reached out to the Bills and the NFL on the matter. The Bills issued a short statement: “We have spoken to LeSean and have been in contact with the National Football League. We will continue to gather information.”

The league added: "We are reviewing the matter."

McCoy’s agent, Drew Rosenhaus, has not yet responded to a request for comment.

The NFL’s domestic abuse policy was written late in 2014 to impose a minimum six-game suspension for players found guilty of it. However, as the recent three-game suspension for Jameis Winston shows, the league has the ability to reduce punishment on its own terms. Winston was accused to groping an Uber driver in Arizona in March 2016 but was never tried on the matter.

McCoy, who turns 30 on Thursday, is entering his 10th NFL season. He spent his first six seasons with the Philadelphia Eagles before joining the Bills prior to the 2015 season. A six-time Pro Bowler, McCoy became the 30th NFL back ever to pass the 10,000-yard rushing plateau and currently is the second-leading active rusher on an NFL roster, behind only Frank Gore.
