Loaisiga was placed on the 60-day injured list by the Yankees on Friday, retroactive to April 4, with a right flexor strain.
Per Greg Joyce of the New York Post, manager Aaron Boone said it's a "significant" strain. Loaisiga will meet with doctors Friday, and surgery would seem to be on the table. The right-hander ended last season on the injured list with an elbow issue and has a long history of arm problems.
