LANDOVER, Md. --- The Green Bay Packers say quarterback Aaron Rodgers got a concussion against the Washington Redskins.
The Packers did not say exactly when Rodgers was hurt Sunday, but he did not miss any plays in Green Bay's 16-13 overtime loss to Washington.
Rodgers was slow to get up off the field after Green Bay's last offensive play, when he was intercepted by LaRon Landry .
He was 27 for 46 for 293 yards with one touchdown pass and the one interception.
LIONS: Detroit's Calvin Johnson sat out the final few minutes of his team's 44-6 win over St. Louis on Sunday after hurting his shoulder making a diving catch near the sideline.
Johnson said afterward the shoulder was sore before heading quickly to the training room. After coming out of the game, he had his jersey removed on the sideline before the shoulder was wrapped in ice.
The ice wrap was gone by the time Johnson spoke briefly to reporters in the locker room.
Lions coach Jim Schwartz said only that Johnson "landed funny" on the play.
Johnson caught four passes for 54 yards and a touchdown.
REDSKINS: Starting left tackle Trent Williams hurt his left knee in Washington's 16-13 overtime victory over Green Bay.
Williams was hurt on the final play of the fourth quarter, when his knee buckled under him during a runback of an interception. He said his knee "just kind of gave out" and called it "real painful."
RAIDERS: Quarterback Bruce Gradkowski was knocked out of Oakland's win over San Diego in the first quarter with a shoulder injury.
Gradkowski was hit hard by San Diego's Shaun Phillips on a pass play in the final minute of the first quarter. The play was originally ruled a fumble. The Raiders challenged and it was changed to an incomplete pass.
Gradkowski went to the locker room and did not return. He was replaced by former starter Jason Campbell .
FAVRE FOLLIES: NFL Commissioner Roger Goodell said once the league completes its investigation of allegations Brett Favre sent racy messages and lewd photos to a Jets game hostess in 2008, it will "make a determination" if the Vikings quarterback should be punished.
The league is looking into the matter under its personal conduct policy.
Goodell added once the investigation is complete, "we'll make a determination from there."
Should Favre be found to have violated the NFL's conduct policy, he could be fined or suspended.
Deadspin.com posted a story Thursday which included several voicemails allegedly sent by Favre to Jenn Sterger , who worked for the Jets at the time. The Web site posted a video that contained the voicemails and several graphic pictures -- said to be Favre -- that were allegedly sent to Sterger's cell phone.
