Nelson missed his second consecutive practice Wednesday because of what coach Mike McCarthy called an "ongoing" ankle injury. McCarthy said he hopes Nelson will get on the field Thursday for the Packers' final practice of the week. Nelson played sparingly (19 snaps, according to Pro Football Focus) in last weekend's wild-card victory over the Minnesota Vikings, and the Packers have kept the exact nature of his injury quiet.
Let's take a look at the rest of the injury reports for both teams:
Packers: Receivers Randall Cobb (flu) and Jarrett Boykin (ankle) joined Nelson on the sideline. Cobb is expected to be ready for Saturday night's game, however. Safety Jerron McMillian missed Wednesday's practice for personal reasons. All other players had at least limited participation, and tight end Jermichael Finley (hamstring) went full.
49ers: All players had at least limited participation, including defensive lineman Justin Smith (elbow/triceps). Barring a setback, Smith is expected to play Saturday night.
