PFT's Mike Florio predicts that Ezekiel Elliott will suit up in Week 1. In a video, Florio said, “It feels like it’s careening towards the court system… which tells me there’s a very good chance that Elliott will be suiting up” in Week 1.
"I think the way that it's going to go, if recent history holds, he will get an injunction preventing the league from suspending him to start the season, suspending him at all until the litigation is over. And the way these cases move, the litigation won't be over until next year. And right now, this is all lining up for Elliott to serve the suspension, if at all, in the 2018 season and to be able to play in 2017…”
If the suspension is upheld, Elliott needs to be granted an injunction by a judge in order to fight the suspension in court. He also must avoid Commissioner Goodell's Exempt List. Even if he were able to get an injunction, Goodell could put him on the Exempt List and hold him out. It's not clear what the chances are that this will happen. If he gets an injunction and stays off the Exempt List, he's likely to play a full seasons since the case will likely more than a few months to come to a conclusion.
