The Detroit Lions placed quarterback Matt Stafford on the COVID-19 list.

It’s unclear yet if Stafford tested positive or was close to someone that did.

Adam Schefter reported that if Stafford can test negative for the remainder of the week, he’ll be eligible to suit up on Sunday against the division rival Minnesota Vikings.

If he’s in fact sidelined, Chase Daniel or David Blough will draw the start for Detroit on Sunday.
