Dunn is currently limited in Reds camp due to unspecified discomfort, Bobby Nightengale of the Cincinnati Enquirer reports.
Dunn threw a bullpen session last week, but he has yet to return to the mound at the Reds' spring training complex in Goodyear, Arizona. This is concerning news for a pitcher who logged only 81.1 total major-league innings (18 starts) between the 2021 and 2022 campaigns due to right shoulder troubles. He has presumably been sent for tests, and it might already be safe to rule him out for a potential spot in Cincinnati's season-opening rotation.
