CLEVELAND (CBSNewYork) — An NFL player is apologizing for posting a graphic image on Instagram showing a man dressed in all black slitting the throat of a police officer. Cleveland Browns running back Isaiah Crowell, 23, deleted the image he posted on Instagram showing blood gushing out of the officer’s neck. The statement reads: “I am outraged and upset by the deaths of Alton Sterling and Philando Castile along with so many others. I am also outraged and saddened by the attacks in Dallas and the deaths of the 5 honorable police officers (Lorne Ahrens, Michael Krol, Michael J. Smith, Brent Thompson, and Patrick Zamarripa) who were providing protection while trying to keep peace. We have to be better as a society, it’s not about color, it’s about what’s right and wrong. I was very wrong in posting that image. Every single life matters, every death as a result of violence should be treated with equal outrage and penalty.” It is not known if the Browns or the NFL will take action against Cromwell over the Instagram post. The third-year running back led the Browns in rushing last season with 706 yards. Crowell rushed for 1,313 yards and 12 touchdowns his first two seasons.
