Gutierrez received a cortisone shot in his right biceps last Thursday and remains in the recovery process, Hank Schulman of the San Francisco Chronicle reports. This would help explain why Gutierrez hasn't seen any usage out of the bullpen since Aug. 24. With the Giants bolstering their relief corps with a slew of September call-ups, Gutierrez won't be rushed back to action until the pain in his biceps fully dissipates.
