Shanahan said the injury is to the lateral collateral ligament on the outside of the knee, caused when he was hit at the end of a 13-yard scramble late in regulation of a 31-28 overtime win over Baltimore.
Griffin will get multiple treatments daily and will likely have to wear a brace for weeks. The next major benchmark is whether he will able to take part when practice resumes Wednesday.
Fellow rookie Kirk Cousins will start if Griffin can’t. Cousins threw a touchdown pass with 29 seconds left in the fourth quarter and ran in the game-tying 2-point conversion.
The Redskins (7-6) have won four in a row and trail the New York Giants by one game in the NFC East.
RAVENS: Cam Cameron was fired as offensive coordinator for Baltimore, which has lost two in a row and is still striving for consistency in the running and passing game.
Cameron ran the offense since the start of the 2008 season for coach John Harbaugh. The Ravens’ attack has repeatedly taken a back seat to its defense, and this year the offense ranks 18th with 344.4 yards per game.
Jim Caldwell, hired as quarterbacks coach before the season, will assume Cameron’s duties. Caldwell was head coach of the Indianapolis Colts from 2009-11.
BOUNTIES: Former NFL Commissioner Paul Tagliabue will rule Tuesday afternoon on the latest round of player appeals in the NFL’s bounty investigation, and any potential punishment will be delayed by a week, a person familiar with the decision said.
The delay is designed to give a federal judge the opportunity to rule on pending motions to throw out the suspensions and remove Tagliabue as the appointed arbitrator, said the person, who spoke on condition of anonymity because no rulings have been announced.
The decision to delay potential sanctions means Saints linebacker Jonathan Vilma and defensive end Will Smith could play Sunday when New Orleans faces Tampa Bay.
COWBOYS: Dallas might make its playoff push without wide receiver Dez Bryant, who hurt his left index finger in a 20-19 victory over Cincinnati. Coach Jason Garrett said Bryant was still being evaluated. The Cowboys play Pittsburgh at home Sunday in a battle of 7-6 teams trying to
keep playoff hopes alive.
BEARS: Quarterback Jay Cutler says he expects to play this week against Green Bay “unless something drastic happens.” He left Sunday’s loss at Minnesota with a sore neck.
49ERS: The team suspended running back Brandon Jacobs for the final three games of the season after a series of posts on social media sites in which he complained about his lack of playing time, including one during the weekend saying he was “on this team rotting away.”
Coach Jim Harbaugh declined to address the comments, even when asked whether Jacobs is still on the team.
JAGUARS: Coach Mike Mularkey was released from a hospital Monday afternoon after a brief stay that included tests after he felt ill. The team offered few details and said he is expected back at work Tuesday.
