The Baltimore Ravens' bout with a COVID-19 outbreak has forced the NFL to postpone the team's trip to Pittsburgh for a second time.

The league announced Friday the Ravens (6-4) will now play the Steelers (10-0) on Tuesday night. The game was originally scheduled for Thanksgiving, then moved to Sunday afternoon after an initial wave of players on the Ravens tested positive for the novel coronavirus.

Additional positive tests, a group that reportedly includes Baltimore quarterback Lamar Jackson, have forced the Ravens to prepare virtually all week.

The postponement forced the NFL to move Dallas' visit to Baltimore next week from Thursday to Monday, Dec. 7. The Steelers will now have a short week to prepare for a visit from the Washington Football Team (4-7) on Dec. 6.

The Ravens-Steelers game — if it happens — will be the second Tuesday game played in the NFL this season. Tennessee played at Buffalo on Oct. 13 following the Titans' bout with COVID-19 in early October.

We appreciate the efforts of the NFL and Pittsburgh Steelers throughout this process, while we all work to create an environment that keeps the health and safety of everyone involved at the forefront of each decision," Ravens coach John Harbaugh said. "Our organization has a plan in place, and we will be prepared to play the Steelers. We thank everyone for their adaptability and look forward to the challenge of facing a very good football team at Heinz Field on Tuesday night."

Robert Griffin III is slated to start at quarterback for the Ravens on Tuesday. He will be taking snaps from a third-string center and handing off to backup running backs Gus Edwards and Justice Hill.

Bears turn to Trubisky as starter

It's been a long way back from a difficult place for Bears quarterback Mitchell Trubisky.

After being benched in Week 3, Trubisky will start against the Green Bay on Sunday night, Chicago coach Matt Nagy said Friday.

Trubisky took all the first-team snaps at practice this week but Nagy had stopped short of designating him the starter, in case Nick Foles was able to return from a hip and glute injury. But Foles was unable to practice again Friday.

"[Trubisky's] worked hard this time that he's been the backup to be prepared for if and when this time comes, whether it's through performance or whether it's through availability or injury with Nick," Nagy said.

The Bears are trying to end a four-game losing streak.

"As far as [who starts] next week or following weeks, it's hard for me to predict that right now," Nagy said.

Foles is doubtful for the game and Nagy said it's still possible Foles could be the backup. Tyler Bray is the other option.

Trubisky suffered a right shoulder injury Nov. 1 against New Orleans while he ran on a zone-read, his only play since being benched against Atlanta in Week 3. Foles' injury occurred on a sack in the fourth quarter of a 19-13 loss to Minnesota on Nov. 16.


• Bengals running back Giovani Bernard is questionable for Sunday's game against the Giants after a recent concussion. He has been starting for the Bengals (2-7-1) since Joe Mixon went out with an injured foot on Oct. 18. Bernard's concussion was first reported by the team Wednesday but he practiced fully Friday.

• Cowboys offensive linemen Zack Martin (left calf) and Cam Erving (sprained right knee) will be out several weeks if not longer after getting injured in Dallas' Thanksgiving loss to Washington.

• The Raiders will get back at least one of the starting defensive players who missed last week's game on the COVID-19 list. Linebacker Cory Littleton will play when the Raiders (6-4) visit the Atlanta Falcons (7-3) on Sunday. Defensive lineman Clelin Ferrell also may possibility return.

• Chargers cornerback Chris Harris Jr. was activated from injured reserve after missing the past seven games because of a foot injury. Teammate Casey Hayward Jr., meantime, was ruled out because of a groin injury, ending his string of 106 consecutive games — the longest active streak among cornerbacks.
