The Seattle Seahawks lost running back Chris Carson to a foot injury early in Sunday night's game against the Arizona Cardinals, and Carson could miss some time.

Ian Rapoport of NFL Network reported Carson's MRI revealed a mid-foot sprain. The Seahawks have said he is week-to-week, putting his status in doubt at least for next weekend's divisional showdown with the San Francisco 49ers.

Carson had 34 yards on five carries on Sunday and seemed primed for a big game. Instead, it was Carlos Hyde who would get the brunt of the backfield touches after Carson went to the locker room.

Hyde rushed 15 times for 68 yards and a touchdown and also had three receptions in Carson's absence, giving the Seahawks at least some semblance of a running game. It would seem the 30-year-old will be the featured back in the event Carson is forced to miss extended time, so Hyde's productiveness was a positive for Seattle despite the loss.

Whether Hyde can be as efficient as Carson, however, remains to be seen. Carson was averaging 4.9 yards per carry while also racking up 22 receptions through his first six games, and that includes Sunday's shortened outing.

Seattle has traditionally had to rely on Russell Wilson and the passing game for big plays, but the ability to establish the run and keep opposing defenses off balance opens things up for Russ and Co.

Then again, there is still a chance Carson could play in Week 8. He suffered a sprained knee in Week 3 against the Dallas Cowboys, but was back on the field in Week 4 against the Miami Dolphins.

In any case, the Seahawks will hope this latest malady is not a lingering issue for Carson as they hope to get back on track against the Niners next weekend.
