The San Francisco 49ers have released wide receiver Marlon Moore.

It was likely that they did so to create a roster spot for wide receiver Mario Manningham, who's eligible to be activated from the physically unable to perform list.

Manningham injured his knee last season against the Seattle Seahawks.

Moore caught one pass in six games this season.

The 49ers are on a bye and don't play again until Nov. 10 against the Carolina Panthers.
