Alvarez (shoulder) has been shut down and will be sent to Dr. James Andrews for further evaluation, John Hickey of the Bay Area News Group reports.
Alvarez has battled persistent issues with his shoulder all season, and things seemed to be taking a turn in the right direction when he was sent out on a rehab assignment in late August. However, it appears his shoulder is not responding as hoped, and he will take another trip to visit Dr. Andrews to see where he stands. He could be forced under the knife again if the results are not promising.
