Musgrove was placed on the COVID-19 injured list Friday.
The Padres didn't announce whether Musgrove tested positive for coronavirus himself, so it's unclear if he's merely at risk of missing one start or likely to miss several. He certainly didn't look ill Friday, as he struck out nine batters while allowing just two runs in seven innings against the Cubs. Reiss Knehr was called up to take his place on the roster.
