Boston Red Sox manager Alex Cora tested positive for COVID-19 prior to Thursday's game against the Toronto Blue Jays.
The team said Cora is fully vaccinated and experiencing mild symptoms.
Bench coach Will Venable will assume managerial duties for the time being.
Cora's positive test comes after the Red Sox placed Christian Vazquez, Jonathan Arauz and Kevin Plawecki on the COVID-19 injured list.
"This is the world we live in," Cora told reporters Tuesday. "It's a lot different than '20 and last year. I've been in a hotel for several days because one of my kids tested positive.
