FFToday's Take:Walker sat out Wednesday's practice as well. Meanwhile, Rishard Matthews returned to a full practice. Walker has battled ankle or wrist injuries for what seems like two months, but he has yet to miss a game. Owners can probably expect a game-time decision with Walker, and Jonnu Smith would be a solid fill-in should Walker be unable to play. Matthews figures to benefit the most, as he seems to be the only receiver to establish a clear chemistry with Marcus Mariota.
