Minneapolis - Minnesota Vikings quarterback Brett Favre left Monday's 40-14 loss against the Chicago Bears with a concussion.
In the second quarter, Favre dropped back to pass and was wrapped up by Corey Wootton, who slammed Favre to the ground as the quarterback landed on his left shoulder.
Staff came out to tend to Favre, who walked off the field under his own power before Minnesota punted the ball away.
"It's one of the few times I kinda went blank there for a while, in my career," said Favre. "Just the way I was slung around on the turf, I wouldn't say it was necessarily the hit."
Later in the post-game press conference, Favre was asked whether he'll play again.
"You know, I don't know with this concussion. Based on the time and based on my decision making, I probably shouldn't tell you one way or the other right now."
Coming into Monday, Favre was listed as out for the game, but his status was upgraded to questionable earlier in the day. He started the game one week after his streak of 297 consecutive starts came to an end.
"I woke up this morning and sent (Minnesota head coach) Leslie (Frazier) a message that, crazy as it may sound, that I was considering playing," said Favre. "I didn't get a message back from him 'til this morning. It was, 'Hey, if we can work it out we'll work it out'."
In addition to losing Favre, Minnesota was playing the game without star running back Adrian Peterson, who was out with ankle and knee injuries.
Peterson, currently eighth in the NFL in rushing yards (1,149), had not missed a game since Week 12 of his 2007 rookie season.
