Delanie Walker was on hand for the start of the 49ers' Wednesday practice, the first session he has attended since breaking his jaw in two places Dec. 24. Walker was wearing a black jersey for the start of practice that designates him as someone who is to avoid contact, and he had a clear face shield on his helmet.
Whether he plays Sunday still is up in the air and Jim Harbaugh - always stingy about medical information - is likely to keep Walker's status cloudy up until kickoff. Walker led the 49ers in receiving when they played the Giants earlier this year and would be a welcome addition to a pass-catching corps that could be without Ted Ginn on Sunday. Ginn (ankle, knee) was not seen at practice.
As was the case last Wednesday, Ray McDonald (hamstring) worked out on a side field with trainers instead of with the defensive linemen. McDonald clearly was not recovered from the injury Saturday and surrendered a large amount of snaps to Ricky Jean Francois.
In addition, center Jonathan Goodwin (calf) was an observer in today's practice. He left the game for a series against the Saints. Safety Dashon Goldson (ankle) came out of the game in the tird quarter after missing Marques Colston on a long pass play. He missed two snaps but returned. Receiver Kyle Williams was no longer wearing the black jersey he was in last week.
Ginn (knee), Goldson (ankle), C Jonathan Goodwin (calf) were listed as "did not practice" on today's participation report. Walker (jaw) was listed as limited. McDonald was not listed at all, implying that he took part in a full session once individual drills.
For the Giants, RB Ahmad Bradshaw (foot) did not practice. He missed the team's earlier meeting this year. LB Mark Herzlich (ankle), QB Eli Manning (illness), DE Justin Tuck (shoulder), DE Osi Umenyiora (ankle, knee), CB Corey Webster (hamstring) were limited. As previously reported, Manning is dealing with a stomach flu and was relieved by David Carr during Wednesday's practice.
