The Las Vegas Raiders have placed seven more players on the reserve/COVID-19 list, bringing the number to 11 ahead of this weekend's game against the Kansas City Chiefs.

"We practiced today and we'll be ready for the game on Sunday," Jon Gruden said after an initial report said "nearly the entire Raiders starting defense" was going on the list.

"It's what you have to do. Everybody has to adapt to a lot of things in every phase of life. We had to go through some things before. We'll be there on Sunday and we'll be prepared. We're excited to compete."

Safety Johnathan Abram, defensive tackles Maliek Collins, Johnathan Hankins and Kendal Vickers, defensive end Arden Key, cornerback Isaiah Johnson and practice-squad defensive end David Irving went on the list as high-risk close contacts a day after defensive end Clelin Ferrell and defensive back Lamarcus Joyner went on the list.

Ferrell went on the list after a positive test.
