Hendriks said Friday that he will receive a cortisone injection in his right elbow Monday, Ian Browne of MLB.com reports.
Hendriks added that an MRI revealed fluid sacs near his right elbow, which could be taken care of with a cortisone shot, per Jen McCaffrey of The Athletic. Hendriks is hoping to join the Boston bullpen for the last week or two of the regular season, but that will largely depend on the Red Sox staying in the AL wild-card race. He's in the final stretch of his recovery from Tommy John surgery that he underwent in August of 2023.
