Brightwell was activated from the reserve/COVID-19 list Monday, Dan Salomone of the Giants' official site reports.
Dan Duggan of The Athletic confirms that Brightwell actually tested positive for COVID-19, but the rookie running back has evidently recovered. If any lingering effects of the virus don't prevent Brightwell from suiting up Monday in Tampa Bay, his role will depend on the health of Saquon Barkley (ankle) and Devontae Booker (hip), who are both well above Brightwell in New York's backfield pecking order when healthy.
