K'Waun suspended, but 49ers designate Mostert, Wilson to return originally appeared on NBC Sports Bayarea
The 49ers likely were going to be without nickel back K'Waun Williams for at least the next two games, but now it's a certainty.
Williams was suspended by the NFL for two games without pay on Tuesday for violating the league's policy on performance-enhancing substances. He'll be eligible to return to the active roster in Week 14.
Williams hasn't played since the 34-17 loss to the Green Bay Packers in Week 9, during which he sustained a high-ankle sprain that was expected to keep him out for an extended period. There was a strong chance he wouldn't have been able to play until Week 14 at the earliest, so in that respect, his suspension doesn't hurt the 49ers all that much.
Unrelated to Williams' suspension, the 49ers made a series of roster moves on Tuesday.
Running backs Raheem Mostert and Jeff Wilson Jr. were designated to return from injured reserve and had their practice windows opened. They each have a 21-day window to practice with the team before San Francisco must decide whether to activate them to the active roster or leave them on IR for the remainder of the season.
Additionally, the 49ers signed safety Chris Edwards to the 53-man roster and signed safety Kai Nacua and receiver Shawn Poindexter to the practice squad.
