The injury came when Favre was sacked by linebackers LaVar Arrington and Jeremiah Trotter on second down at the Green Bay 24, when Favre sacked for a loss of 12 yards.
We think it's a (sprained) LCL," Green Bay coach Mike Sherman said. "He wanted to go back in the ball game, you know Brett, we'll wait until tomorrow when the swelling goes down."
Backup Doug Pederson came in the rest of the way, and was unremarkable, but did nothing to hurt the Packers' chances and was successful completing the astutely called high-percentage passes. He finished 9-of-17 for 78 yards and no touchdowns or interceptions.
"(Offensive coordinator) Tom Rossley did a good job," Sherman said. "I would have liked to support what the defense did based on the turnovers we have, but the backup qb doesn't get any reps in practice, he did a stellar job.
"Doug's job was not to throw an interception. a great team effort, worked through adversity, we lost our quarterback and there were some calls who didn't go our way, but we dealt with it and did what we have to do," Sherman said.
It was an amazingly resourceful defense that made the difference.
Tabbed "Team Takeaway" by the Packer radio broadcast team, the Packer defense came up with 5 takeaways. The fumble recovery was their best defense and offense after Favre's injury.
"We talked during it the week, they were obsessive toward the football," Sherman said.
The Packers also came up with six sacks compared to the 'Skins one sack -- although it was that one that could make a difference in this so-far stellar season.
Green Bay had just 243 yards of offense against a tough Washington defense. Ahman Green started quickly with 71 first-half yards, but was held to next-to-nothing in the second half. However, he did manage an 8-yard TD run which sealed the game and gave him all three TDs (all on the ground) in the game. It was the first 3 rushing TD game of his career.
Ryan Longwell shook off last week's miscues and connected on all three attempts.
"This was a a phenonemal effort with what our line had to do," Mike Sherman said. "I am pleased, the aomount of adversity we have had to deal with on a regular basis, the guys hang in there and keep battling. I'm impressed with the effort and the passion, these guys are proud to be Green Bay Packers and they show it on the field."
