San Francisco 49ers WR Mario Manningham (knee) is roughly a month away from returning to action on the field, and the competition behind WR Anquan Boldin will be furious. WRs Kyle Williams, Ricardo Lockette, A.J. Jenkins, Quinton Patton and Marlon Moore will be looking to step up in the absence of WR Michael Crabtree (Achilles’).
