Matthew Stafford will start Sunday as long as he passes one more COVID-19 test.
The Lions removed the quarterback from the COVID-19 reserve list Saturday.
The negative tests all week allow him to return, though he missed practice all week. Stafford was allowed to participate in the virtual meetings.
The Lions had COVID-19 issues with players or staffers for four consecutive days.
The Lions also activated defensive end Austin Bryant off the physically unable to perform list, placed cornerback Darryl Roberts on injured reserve, ruled out guard Joe Dahl with a back injury and elevated offensive lineman Marcus Martin from the practice squad.
