FILE - In this Aug. 19, 2019, file photo, Denver Broncos outside linebacker Bradley Chubb looks on during an NFL preseason football game between the Denver Broncos and the San Francisco 49ers in Denver. Many players polled by The Associated Press over the last couple of weeks say they are scared to return to work without a cure or a vaccine for the coronavirus. By and large, however, those same players say they trust the protocols the NFL will have in place by the time practices resume and games return. (AP Photo/Jack Dempsey, File)
