Thanksgiving is tomorrow but the 49ers did get a practice in today, which means time for the first injury report of the week.  As you'll see, it's a good news/bad news report for the 49ers.

San Francisco 49ers
Out: S Dashon Goldson (knee), KR Allen Rossum (ankle)

Did Not Participate in Practice: CB Walt Harris (hamstring), LB Takeo Spikes (not injury related), LB Patrick Willis (ankle)

Limited Participation in Practice: WR Arnaz Battle (foot), WR Josh Morgan (groin)

Buffalo Bills
Did Not Participate in Practice: DE Copeland Bryan (foot), LB Keith Ellison (ankle), CB Jabari Greer (knee), LB Teddy Lehman (hamstring), TE Robert Royal (hamstring), DE Aaron Schobel (foot)

Limited Participation in Practice: S Donte Whitner (shoulder)

Maiocco indicated Harris, Spikes and Willis are all more than likely going to play.  The bad news comes in the form of Allen Rossum being ruled out.  He has been one of the best kick returners in the league and losing him is definitely a blow to the 49ers.  Based on this past week, Delanie Walker will likely be the guy returning kicks.  If he's active I wouldn't mind seeing Reggie Smith get a shot.  He returned punts at Oklahoma so why not give him a shot at that since he's not doing much else?

The good news is that Battle and Morgan have both returned to the practice field.  Given the cold weather I'm not optimistic that Morgan will play.  He's got a groin injury and as with hamstrings I don't imagine cold weather is all that good for them.  And I'd like to see a little bit more of Dominique Zeigler, which would be tough if Morgan and battle were 100%.
