TMZ reports:

The witness says she saw Ezekiel 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.

In the video, you can see the victim writhing in pain on the ground. We're told he was on the ground for a few minutes.

Not the way the Cowboys wanted to open training camp. Elliott was already facing a suspension from the NFL reportedly, and this could add to their ire. So, if their star back misses the first four games, where do the Cowboys go? Certainly an interesting start to the NFL preseason.
