An article is configured for transferring tissue cores from a patient donor site to a patient wound site. The article includes a matrix construction of resilient elastomeric polymer material to support an array of tissue core locators individually defining an opening and individually configured to: (1) receive a tissue core from the donor site into the opening, (2) resiliently hold the tissue core at the opening until and after the sheet is placed upon the wound site, and (3) release the tissue core when the sheet is removed from the wound site at a time that is between 2 and 29 days after the sheet is placed upon the wound site.
