One of the top sports orthopedic surgeons in the country says 49ers quarterback Alex Smith will not need surgery on his separated shoulder. According to ESPN, Dr. James Andrews of Birmingham, Alabama provided a second opinion confirming the original diagnosis that Smith had suffered a grade three shoulder separation. An MRI taken Monday questioned the extent of the ligament damage to the shoulder which led to an additional review by Dr. Andrews. It remains unknown how long Smith will be out, but he could miss anywhere from three to eight weeks. Trent Dilfer will get the start at quarterback this Sunday against the Baltimore Ravens. San Francisco has a “bye week” October 14th.
