It's been a tough week for NFL running backs on the injury front.
With Saquon Barkley and Austin Ekeler both already expected to miss an extended period of time, Nick Chubb of the Cleveland Browns and Jamaal Williams of the New Orleans Saints both went down with their own injuries in their respective Monday night matchups.
Chubb in particular had a bright start to the season with 106 yards in the Browns' season-opening win over the Cincinnati Bengals. He had to be carted with what looked like a nasty knee injury against the Pittsburgh Steelers on Monday.
