The Guardians placed DeLauter (rib) on the 10-day injured list Wednesday, Tim Stebbins of MLB.com reports.
Since his IL stint is retroactive to Sunday, DeLauter will be eligible for activation June 24, but a return in the minimum amount of time could prove to be ambitious for the outfielder after an MRI on Tuesday revealed a small right side rib fracture in addition to bone bruising. Cleveland recalled Kahlil Watson from Triple-A Columbus in a corresponding move, but he'll be on the bench Wednesday against the Brewers while the Guardians go with Steven Kwan, Petey Halpin and David Fry as their starting outfielders. A clearer target date for DeLauter's return should emerge once he's able to resume full baseball activities.
