Fairbanks will undergo surgery to treat thoracic outlet syndrome, Christina De Nicola of MLB.com reports.
Fairbanks was ruled out for the season upon landing on the injured list Tuesday with nerve irritation in his right hand, and now that he's confirmed to be dealing with thoracic outlet syndrome, he'll go under the knife to treat the issue. A timeline for his return should emerge after his procedure, though he'll likely have to sit out the first portion of the 2027 campaign.
