The Phillies have canceled Thursday's workouts after two staff members tested positive for COVID-19.
The two positive tests came from Wednesday's round of testing. The team said no players tested positive for the virus but one coach and one home clubhouse staff member did.
"All activity at Citizens Bank Park has been canceled today and until further notice," the Phillies said in a statement.
The decision comes amid a disastrous week in Major League Baseball where over a dozen Marlins players tested positive for COVID-19 following their weekend series in Philadelphia. The Phillies have been in isolation since then and were scheduled to resume play on Saturday with a doubleheader against the Blue Jays.
