The 49ers and Rams released their first injury reports for their Week 13 matchup and we have some changes to include this week.

The big news for the 49ers is Delanie Walker will sit out and David Akers was limited in practice. Walker injury his hip late in the 49ers win over the Saints and needed a cart to get on the bus. He was apparently walking around fine today according to various twitter reports, but the 49ers sat him out for the day.

Coach Harbaugh first indicated during his press conference that Akers would be limited in practice as he worked through something. It is listed as a pelvis injury, which can't be good for a kicker. Akers has struggled from distance this season, so one has to wonder how much this has to do with it, if anything at all. The 49ers brought in some kickers, but I would imagine any signing probably does not happen until Saturday so the 49ers can see how Akers is feeling at that point. The team still has one roster spot open.

The big injury for the Rams is Danny Amendola. The wide receiver is injury prone and is dealing with a foot injury right now. Amendola torched the 49ers last game with 11 catches for 102 yards. He is Sam Bradford's go-to guy, so he will be an injury to watch this week. Steven Jackson sat out practice as well, but that is likely a veteran's day off.
