Not sure where you are getting that from that story.
According to Hendrick Motorsports, Jr. definately suffered the concussion on Sunday at Dega.
Now he did take a really hard lick during testing at Kansas in August, and he did suffer a concussion in 2002 in a wreck at California.
Got it from the link supplied.
Jr. says it happened in KS

Listen to the video with Ricky Craven which mentions the Kansas crash and concussion...... Who knows all the info or at least it seems to be coming in bits and pieces.
Wreck at KS was 40G’s. He knew he got hurt, raced anyway and it took a while to feel better.
Wreck at ‘dega was 20G’s. Said he knew it wasn't a bad wreck but had headache after race and waited a while ‘til things cleared up before seeing doctor and making decision to withdraw from season.
