As they get set for their B1G football opener at Minnesota (6:30 p.m. CST/ABC), the Michigan athletic department is experiencing another COVID-19 surge.

The department reported a new single-week high of 26 positive COVID-19 tests (Oct. 17-23), with 25 being student-athletes and one being a staff member, according to MLive.com. The last single-week high was 14 (Oct. 3-9).

Altogether since mid-June, the department has given out 13,734 tests and 131 have been ruled positive. Per MLive.com, the school isn’t disclosing the identities of who’s infected or the teams that they’re on.

Michigan football head coach Jim Harbaugh disclosed on Monday that his team has no positive results but there hasn’t been an update since. Players and staff have been rapid-response antigen tested since Sept. 30, with anyone determined positive has to miss 21 days of competitive activities and spent 10 days in isolation.

Additionally this week, Washtenaw County Health Department put a two-week stay-in-place order for all University of Michigan undergraduates, according to MLive.com. Student athletes are granted an exception ‚Äúprovided that athletic medical staff is present,” during practices and competitions.
