(AP) — Both Saints veteran quarterbacks, Taysom Hill and Trevor Siemian, Minnesota star running back Dalvin Cook and Cleveland center JC Tretter, the NFL Players Association president, tested positive for COVID-19 on Thursday.

But Washington is getting back quarterback Taylor Heinicke.

Hill and Siemian were among nine players for New Orleans placed on the reserve/COVID-19 list. The others include such key players as safety Malcolm Jenkins and tackle Jordan Mills, who is expected to start Monday night against Miami.

The situation left Ian Book, a rookie out of Notre Dame who has been inactive for all 14 games, as the only active quarterback under contract. It appears Book is in line for his maiden NFL regular-season appearance. Running back Alvin Kamara has been the Saints’ emergency quarterback for several seasons and conceivably could take direct snaps as a wildcat threat.

The latest COVID-19 hit to the Saints came as New Orleans awaits the return of coach Sean Payton, who did not travel to Tampa Bay for the Saints’ victory as he has worked from home since testing positive for COVID-19 last Thursday. Saints defensive coordinator Dennis Allen has been serving as acting head coach.

The Browns (7-7), who play at Green Bay on Christmas, got two more players back from the COVID-19 list as linebacker Grant Delpit and rookie offensive tackle James Hudson III were activated.

Stefanski returned to the team on Wednesday.
