49ers put Manningham on injured reserve

The San Francisco 49ers placed wide receiver Mario Manningham on the injured reserve list, the team announced Friday.

The 49ers did not specify Manningham's injury, but the Bay Area News Group reported that Manningham will consult with doctors regarding his knee injury to determine the next step.

Manningham began the season on the physically unable to perform list and was activated to the 53-man roster on November 4. He played in six games, including three starts, this season. He had nine receptions for 85 yards.

Manningham is in his second season with the 49ers after signing with the team as a free agent on March 13, 2012.
