Michael Morse is likely to start the season on the disabled list after receiving a plasma injection:

Johnson also said he believes Morse recently received platelet-rich plasma treatment, a relatively new procedure also referred to as “blood spinning,” in which blood plasma is removed from the body, injected with extra platelets to help the body heal faster and then re-injected into the patient. Yankees star Alex Rodriguez underwent the procedure last winter in Europe, and Orioles pitcher Zach Britton recently had it as well.

I assume he received the treatment to speed the healing process, which means he would have started on the DL anyway.
