Earlier Wednesday, the NFL took the Ravens-Steelers rematch off its Thanksgiving schedule. That game is now on tap for 12:15pm CT Sunday. More is emerging on why the Steelers will see another of their games delayed. The Ravens disciplined a strength and conditioning coach for “conduct surrounding the recent COVID-19 cases that have affected players and staff.” The Ravens are levying the discipline because the unnamed staffer did not report symptoms or consistently wear a mask or a contact tracing device, according to NFL.com’s Tom Pelissero (on Twitter). This is believed to have contributed to the Ravens’ outbreak — one that comes nearly two months after a Titans outbreak altered the Steelers’ schedule. Seven Ravens players and at least five staffers have tested positive for COVID. This will not only weaken Baltimore against Pittsburgh but potentially deplete team’s roster for its Week 13 Thursday game against Dallas.

Several teams shuffled their rosters because of COVID on Wednesday. Here is the latest:

• 49ers left tackle Trent Williams tested positive for COVID-19 last week, per ESPN.com’s Dan Graziano (on Twitter). A cancer survivor, Williams has not experienced issues with the virus yet, Graziano tweets. Williams, who landed on the 49ers’ COVID list earlier this month as a high-risk close contact, is on track to miss San Francisco’s Week 12 game in Los Angeles.
• Six players remain on San Francisco’s virus list. The 49ers removed Arik Armstead and center Hroniss Grasu on Wednesday.
• Browns linebacker Sione Takitaki tested positive Wednesday, according to Mary Kay Cabot of cleveland.com (on Twitter). Takitaki played against the Eagles and returned an interception for a touchdown. The Cleveland starting linebacker’s positive test follows Myles Garrett‘s. Neither they nor Denzel Ward (injury) will be available for Sunday’s game against the Jaguars. The Browns closed their facility Wednesday, but their Jags game remains on schedule.
• The Bengals placed wide receiver Auden Tate and recently acquired offensive lineman B.J. Finney on their reserve/COVID-19 list. Cincinnati has seen staffers test positive, with D-line coach Nick Eason being the most recent. Eason was alerted of his positive test Tuesday. The Bengals now have five players on their reserve/COVID list.
• Christian Wilkins is off the Dolphins‘ COVID list. Wilkins was not reported to have tested positive, but the second-year defensive lineman still missed two games after landing on the team’s virus list.
• The Raiders activated Cory Littleton from their COVID list. The high-profile free agent addition has been out for two weeks due to a positive coronavirus test. Las Vegas’ defense remains shorthanded due to virus issues, with Clelin Ferrell testing positive last week and Lamarcus Joyner missing Sunday’s Chiefs game because of his status as a close contact.
• Dante Fowler also tested positive two weeks ago and missed the Falcons‘ Week 11 game, but the big-ticket free agent addition is off the list now and on course to return to Atlanta’s lineup Sunday.
• The Vikings and Chargers also removed players from their respective virus lists Wednesday. Minnesota activated guard Dru Samia; Los Angeles activated cornerback Brandon Facyson.
