Saturday’s NFL preseason game between the San Francisco 49ers and Houston Texans may provide former Utah running back Joe Williams with his best chance yet — i.e. a high number of snaps — to prove he deserves a spot on San Francisco's 53-man roster.
Williams currently finds himself behind Jerick McKinnon and Matt Breida on the 49ers' depth chart and in competition with Raheem Mostert for the third running back spot. McKinnon (calf strain) and Breida (separated shoulder) suffered injuries in recent days that will keep both players from action this week and Breida through the rest of the preseason, according to the San Francisco Chronicle.
