Penn is looking for tenants to fill two empty area storefronts, but has not yet made a decision about any potential new businesses on campus.
University Jewelers, located at 3401 Walnut Street, closed this past Monday.
It is the second store to close or move this academic year.
The other is the former Eastern Mountain Sports store located on 36th Street between Sansom and Walnut.
Several businesses have expressed interest in the properties, but the University is waiting for the right fit, Facilities spokesman Andrew Zitcer said.
The recent turbulence in the economy is another reason for the delay - despite University City's continued growth, retailers are more wary of expanding.
Zitcer said Facilities and Real Estate officials hope to find a tenant for one of the vacancies by the end of the semester.
