You probably have heard that Stephen Jackson will miss at least a week with a groin tear.

I also read that the 49ers will be without their stud tight end Vernon Davis for a while with a strained ligament in his knee.

According to their depth chart, a guy named Billy Bajema will start in his place. Billy Bajema?

It also sounded like one of their starting safeties, Mark Roman, has an elbow injury of unknown severity.

More on this as we near the game.
