Panthers running back Jonathan Stewart re-injured his right ankle Monday night versus the Eagles in addition to suffering a high-ankle sprain to his left ankle. SOURCE: Joe Person, Charlotte ObserverFantasy Spin:Stewart missed two of the first three games this season after spraining his right ankle during the preseason. Now he's dealing with two sore ankles and hasn't practiced this week. We consider him doubtful to play Sunday against the Kansas City Chiefs. DeAngelo Williams will be the de facto starter but hasn't been fantasy worthy in his other starts this season.
