According the the Denver Post, coach Gary Kubiak said Williams suffered an Achilles injury, which Williams later confirmed, via Instagram.
Williams was vying for the starting punt return position and was going up against Jordan Norwood, Solomon Patton, Isaiah Burse and Emmanuel Sanders. The 49ers selected Williams in the sixth round of the 2010 NFL Draft.
