The Cardinals preserved David Johnson on a day they had just two running backs active. D.J. Foster injured his hamstring during Thursday's practice and was ruled out by Friday, leaving Johnson and Chase Edmonds as the only two active backs. If Foster didn't get injured there was a good chance Johnson wouldn't have played this week.
Edmonds was seen throwing up on the sidelines at one point, and Johnson re-entered the game, but Edmonds insisted on returning. While this wasn't exactly ideal for fantasy owners, the Cards were looking to keep Johnson healthy for the long run. If Edmonds is still out there on your wire, he's going to be worth an add. Johnson owners may also want to think about trading for Edmonds if he's already been snagged.
