Fairbanks left Monday's game against the Red Sox after suffering an apparent injury, Isaac Azout of FishOnFirst.com reports.
Fairbanks called for the trainer after issuing a walk to the lone batter he faced in the top of the ninth inning, and he walked off the mound to the clubhouse after a brief conversation. The nature of the injury is unknown at this time, but he'll presumably be sent for further evaluation after exiting.
