The Buffalo Bills have placed four players on the reserve/COVID-19 list, one of them cornerback Josh Norman after he tested positive for the virus.

Norman’s test result means he has not travelled with the team for Sunday’s clash with the Arizona Cardinals, as the in-form Bills aim to stretch their unbeaten run to four games.

The AFC East leaders will also be without another cornerback in Levi Wallace, as well as safety Dean Marlowe, leaving them with a depleted secondary against Cardinals quarterback Kyler Murray.

Tight end Tyler Kroft is the other player added to the list, as per the NFL’s protocols with regards close contact amid the ongoing pandemic.

“The Bills were informed this morning that CB Josh Norman has tested positive for COVID-19,” Buffalo said in a statement on Saturday.

“Norman was placed on the reserve/COVID-19 list and will not travel and play in Sunday’s game at Arizona.

“Per NFL contact tracing protocols, three others players – TE Tyler Kroft, CB Levi Wallace and S Dean Marlowe – have been defined to have been in close contact and have been placed on reserve/COVID-19 list. They will not travel for Sunday’s game.

“Defensive assistant coach Leonard Johnson will not travel to Arizona as well.”

The Bills sit at 7-2 for the season, the franchise’s best start through nine games since 1993, a campaign that saw them go on to make their fourth straight Super Bowl appearance.
