49ers waived WR Kyle Williams. Williams "started" five of the 49ers' first nine games at receiver, but caught just 12 passes for 113 yards. He was also dead last in the league in punt-return average. Williams was a fringe NFL talent even before tearing his ACL last Thanksgiving, so it was extremely surprising how much time he got with San Francisco's offense. He's unlikely to draw much interest on waivers. The 49ers are moving forward with Mario Manningham opposite Anquan Boldin.
