Rainey (undisclosed) was placed on the COVID-19 injured list Wednesday, Mark Zuckerman of MASNSports.com reports.
Erik Fedde was also placed on the specialized injured list, with one player having tested positive for the virus while the other is out for contract tracing, though it's unclear which is which at this point. Regardless, Fedde and Rainey will be sidelined until they clear the league's COVID-19 protocols.
