With Jon Gruden tendering his resignation Monday amid reports of emails he sent before being hired in 2018 that contained racist, homophobic and misogynistic comments, longtime special Rich Bisaccia makes his debut as interim head coach of the Raiders, and offensive coordinator Greg Olson will be the new voice in quarterback Derek Carr’s ears, calling the plays in a matchup that pits 3-2 rivals seeking their first win in October.

“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.
