The San Francisco 49ers have released wide receiver and return man Kyle Williams.

Williams' agent, Wynn Silberman, says the move has been made by the reigning NFC champions, though the 49ers had yet to formally announce Williams' departure.

San Francisco (6-3) is looking for more production in the passing game, and Williams had fallen on the depth chart with the return of Mario Manningham for Sunday's 10-9 loss to the Carolina Panthers. In addition, 2012 leading wideout Michael Crabtree resumed practice last week for the first time since undergoing surgery in May for a torn right Achilles' tendon.

The 25-year-old Williams, a native of nearby San Jose, has 12 catches for 113 yards and no touchdowns.

He was a sixth-round pick by the 49ers in the 2010 NFL draft out of Arizona State.
