The Twins did not allow Duffey (shoulder) to play catch Monday, Mike Berardino of the St. Paul Pioneer Press reports.
Twins manager Paul Molitor described Duffey's injury as a "flesh wound" when asked about the ailment Monday. For now, Duffey is day-to-day, along with teammate Ervin Santana (back), which could leave the Twins in a difficult spot with their rotation later in the week.
