Michigan football won’t be back at practice on Tuesday.

Despite earlier reports that some of the presumptive positive COVID-19 tests had come back negative upon PCR testing, the program will continue to hold activities virtually, program spokesman Dave Ablauf said in a statement.

“Out of an abundance of caution, we will again hold all team activities in a virtual format today,” Ablauf said. “We will continue to follow the prevention protocols and recommendations of our medical professionals and the health department, and do everything to keep our focus on protecting the health, safety and welfare of our student-athletes and staff.”

Michigan coach Jim Harbaugh didn’t say in a news conference on Monday how many presumptive positive tests the Wolverines had, or whether they had reached any of the Big Ten’s positivity thresholds. 

It’s also unknown how many players could be affected by contact tracing, even if they test negative for COVID-19.

As of now, it’s unclear whether Saturday’s game against Maryland will be played as scheduled.
