Former Michigan State star running back Kenneth Walker III is questionable to return for the Seattle Seahawks in their game against the Los Angeles Rams Sunday afternoon.

Walker has been one of the best rookies in the NFL this season and is a major loss for Seattle vs. Los Angeles in their quest for a playoff berth. Walker injured his ankle late in the 2nd quarter, leading 14-10.

Walker rushed for just 36 yards Sunday before suffering his injury. The rookie RB has rushed for over 600 yards and touchdowns for the Seahawks already this season.

That’s especially impressive considering he didn’t play for much of the first half of the year.
