The 49ers announced a handful of roster moves on Wednesday. They have signed offensive lineman Michael Dunn and wide receiver Malik Knowles to their 90-man roster. They released defensive lineman Demone Harris and waived running back Corey Kiner with an injury designation in corresponding moves.

49ers wide receiver Jacob Cowing did not practice Wednesday. Coach Kyle Shanahan said on KNBR that Cowing is dealing with the same lingering hamstring injury that sidelined him early in camp.
