Earlier Tuesday, an unidentified Instagram user posted a graphic image of a woman with cuts and bruises on her face along with a message that accused McCoy of beating the woman. The post also included allegations that McCoy beat his son, beat his dog and used “illegal steroids.”
McCoy responded shortly after noon ET Tuesday on his own Instagram account, saying that the “totally baseless and offensive claims made against me today on social media are completely false.”
The Bills also are aware of the allegations, a source told ESPN’s Dianna Russini. McCoy’s agent Drew Rosenhaus and the NFL did not immediately respond to requests for comment.
ESPN’s Mike Rodak contributed to this report.
