Quarterback Brett Favre suffered a concussion in the third quarter of the Packers' 14-7 home loss to the New York Giants when defensive lineman William Joseph knocked him to the ground.
Favre, whose head bounced off the grass, sat out two plays before returning to throw a 28-yard touchdown pass to Javon Walker on fourth and five. After celebrating the touchdown with Walker, Favre was summoned to the sideline, where medical personnel said he displayed signs of a concussion.
Coach Mike Sherman acknowledged he shouldn't have sent Favre back into the game.
"Well, he was standing there on the sideline. I said, 'Are you okay?' He said yes. So, I put him back in," Sherman said. "He threw the touchdown pass, and then the doctors told me after that they didn't want him back in the ballgame.
"The doctors hadn't necessarily cleared him, so I was in error in putting him back in there."
Favre's touchdown extended his streak to 29 consecutive games with at least one scoring pass, third-longest in NFL history behind Dan Marino's 30 and Johnny Unitas's 47.
The last time Favre was held out of the end zone was Oct. 20, 2002, when Redskins linebacker LaVar Arrington knocked him from the game with a sprained knee.
That also was the last time Favre missed a significant portion of a game. He missed the final series last week at Indianapolis after getting kicked in his left hamstring, leaving him with a softball-sized bruise.
He has started 212 straight games, counting playoffs, an NFL record for quarterbacks.
