Six players put on NFL's reserve/COVID-19 list

Some players won't be appearing at training camp this week for various reasons, and six players have been placed on the NFL's reserve/COVID-19 list in lieu of that, according to ESPN. 

The six players are Cleveland Browns running back Dontrell Hilliard, Dallas Cowboys wide receiver Jon'Vea Johnson, Baltimore Ravens defensive back Nigel Warrior, Cincinnati Bengals defensive end Kendall Futrell, Browns defensive back Jovante Moffatt and Kansas City Chiefs wide receiver Aleva Hifo.

Being placed on the list does not mean a player has tested positive for the coronavirus, though it's possible they were exposed to it. Teams aren't allowed to reveal why a player has been put on the list, but can activate the player as soon as he's healthy.

Warrior, Futrell, Moffatt and Hifo all are undrafted rookies while Hilliard rushed for 49 yards and two touchdowns last season with the Browns. Johnson, who is entering his second NFL season, spent last year on the injured list.
