Houser was placed on the COVID-19 injured list Friday after testing positive for the virus, Adam McCalvy of MLB.com reports.
Houser began feeling symptoms earlier Friday before the positive test came in. The right-hander is the ninth Milwaukee player to be placed on the COVID-19 list in the past 11 days. He'll now quarantine for a minimum of 10 days before he's able to rejoin the team, meaning he'll likely miss at least two turns through the rotation.
