Ferguson will open the season on the injured list due to an oblique injury, Gordon Wittenmyer of The Cincinnati Enquirer reports.
Manager Terry Francona said that it is a mild oblique injury and that Ferguson will be out "a couple of weeks" and that "he has to heal the way it heals," per Charlie Goldsmith of Fox 19 Now Cincinnati. The southpaw was signed by the Reds in December and is likely to fill a middle-relief role when healthy.
