Dallas PD says it is investigating an alleged assault Sunday night. No arrests made, no suspect listed, no mention of Ezekiel Elliott. https://t.co/UHZtVR51TJ2017-7-17 14:04:37
TMZ Sports later shared video after the incident, reporting the man attacked was "involved in a verbal altercation with a woman" in Elliott's group, with the running back stepping in.
TMZ's witness says she saw Elliott "punch the man—corroborating the story the victim's friend told police. However, cops at the scene could not confirm Zeke was the attacker and he has not been arrested or charged with a crime."
The man told police his nose was broken, but he "appeared to be extremely intoxicated and couldn't remember who hit him." It was the man's friend who identified Elliott as the attacker, saying, "It was that Dallas Cowboys running back."
Fisher's account of the evening is that Elliott was involved in an altercation where another person was punched. Police and an ambulance arrived on the scene; it is unclear if anyone was injured.
Elliott is currently under NFL investigation for alleged incidents of domestic abuse against a woman in 2016. The league gave the reigning Rookie of the Year a detailed report on its findings over the weekend, and Elliott was preparing a response before this incident became public.
Elliott also received negative publicity when he pulled a woman's shirt down in public at a St. Patrick's Day party in March. Schefter reported the NFL could look to suspend Elliott for one or two games under its personal conduct policy, highlighting his multiple off-field transgressions.
"The NFL is looking to pin something on him," a source told ESPN.com's Adam Schefter.
"I would rather it not drag on this long," Elliott said in January. "If there was something to find, which there's not, they would've found it by now. The police did a very thorough investigation. It just seems like they're dragging their feet right now. Who knows, man? I'm just ready for it to end."
