Richardson was held out of practice on Tuesday, which mainly seems like a precaution, especially since this is the same knee that was initially scoped in February.
While many people are quick to panic or say “This is why you don’t draft a running back so high,” being sore is simply part of the game. If Richardson does sit out Friday’s game, it shouldn’t make a difference. With four meaningless preseason games, it wouldn’t be such a bad thing for him to miss one.
Obviously it would be good for him to see real action, but there is no question that he can play and his spot on the roster is certainly secure. If anything, this is the perfect opportunity to see how the backup battle between Montario Hardesty and Brandon Jackson is shaping up.
