Injury updates: Offensive tackles Ronnie Stanley (right knee strain) and James Hurst (undisclosed) returned to practice Monday, although they were not on the field at the end of the session. The duo did not practice Wednesday and Thursday and did not play Saturday night, but Harbaugh was happy to see them back. “It’s great to get healthy on the offensive line,” he said. “It’s great to see those guys out there practicing. Just as I mentioned last week, they were short term-type injuries, and that’s fortunately what they turned out to be.” … The team practiced without safeties Bennett Jackson (undisclosed) and rookie DeShon Elliott (fractured left forearm), cornerback Maurice Canady (muscle strain), defensive tackle Willie Henry (umbilical hernia surgery) and three rookies in tight end Hayden Hurst (stress fracture in foot), inside linebacker Alvin Jones (unspecified) and offensive tackle Greg Senat (right foot).
