Lauer has tested positive for COVID-19, Adam McCalvy of MLB.com reports.
Lauer is the seventh player for the Brewers to land on the COVID-19 IL during the team's recent outbreak. The southpaw was tentatively scheduled to make his next start Monday against the Cubs, but the team hasn't announced who will take his place in the rotation. The 26-year-old will be away from the team until he tests negative and clears the league's health and safety protocols.
