Urshela (hamstring) suffered a setback and isn't expected to return from the injured list this week, Lindsey Adler of The Athletic reports.
The 29-year-old was targeting a Wednesday activation, but that's no longer possible after he suffered a setback while participating in ground ball drills Monday. The severity of the setback remains unclear, though it's safe to push back Urshela's expected return to at least next week.
