Ezekiel Elliott Is All Smiles Again After Domestic Violence Allegations

Ezekiel Elliott doesn't look like he's too worried about last week's domestic violence allegations -- posting a photo to social media with a big ol' smile on his face.

TMZ Sports broke the story ... Elliott's ex-GF claimed the Dallas Cowboys star struck her during a parking lot altercation early Friday morning -- and later claimed he had a history of violence against her.

But cops spoke with 4 witnesses who say they never saw Elliott lay a finger on the woman -- and in the end, officers did NOT arrest Elliott because they didn't feel there was enough evidence to prove he committed a crime.
