When Walker's message was relayed to 49ers coach Jim Harbaugh during his Wednesday press conference, he was hopeful but non-committal.Walker was a key component to the 49ers' offense before he was injured in the regular-season finale against the Seattle Seahawks. He had six receptions for 69 yards in the 49ers' 27-20 win over the Giants in Week 10.
Three 49ers -- wide receiver Ted Ginn (knee), safety Dashon Goldson (ankle) and center Jonathan Goodwin (calf) -- were held out of Wednesday's practice. All three suffered injuries in the divisional playoff win over the New Orleans Saints.
