“I’m not going to say anything other than I’m optimistic, but I’m not a mind reader,” coach Jon Gruden said Thursday. “I just know he had an injury that caused him to miss the game last week and I’m respectful of that. If for some reason Carr can’t play, Marcus Mariota is in position to make his first start for the Raiders. S Erik Harris and DB Daryl Worley also are on the COVID-19 list. ... WR Henry Ruggs III returned to practice from the COVID-19 list and Gruden is hopeful he will play.

The Las Vegas Raiders fired defensive coordinator Paul Guenther after he failed to make any significant improvement for the unit in nearly three full seasons on the job. Defensive line coach Rod Marinelli will take over on an interim basis for the rest of the season. Marinelli has previously served as a head coach in Detroit and defensive coordinator in Chicago and Dallas. He has long ties to Gruden, having served as his defensive line coach for the Super Bowl champion Tampa Bay Buccaneers in 2002 and then rejoining Gruden this season on the Raiders. We got a chance to win all three and see what happens at the end,” defensive tackle Johnathan Hankins said before the announcement.
