Dale Jr. Out For Next 2 Weeks In NASCAR

This is interesting: From ESPN: Dale Earnhardt Jr. will miss the next two races with his second concussion in the past six weeks, all but ending the championship chances of NASCAR's most popular driver.
The first concussion, suffered in a crash during an Aug. 29 tire test at Kansas, went undiagnosed until Wednesday, when Earnhardt was examined in Charlotte because of lingering effects from Sunday's crash at Talladega.
Earnhardt said he didn't report symptoms he was having after the Kansas crash for fear of being taken out of the car for the start of the Chase for the Cup.
"I remember everything about that accident, everything after that accident," Earnhardt said. "But I knew I didn't feel ... you know your body and how your mind works. I knew something was just not quite right. I decided to push through and work through it. I had concussions before and knew exactly kind of what I was dealing with. I felt pretty good after a week or two, definitely 80 to 90 percent after the Chase started. By the time I got to Talladega I felt 100 percent, really good."
Hendrick Motorsports said Earnhardt will sit out races at Charlotte and Kansas; Regan Smith will replace him in the No. 88 Chevrolet.
A source with knowledge of Earnhardt's business told ESPN that his salary from Hendrick to drive the car will not be affected by his missed races. Also, the money paid by his primary sponsors (Amp Energy this weekend and National Guard at Kansas) will not be affected in his absence.  http://espn.go.com/racing/nascar/cup/story/_/id/8489668/dale-earnhardt-jr-concussion-2-races
This just seems strange on so many levels.
First, Junior really ripped into NASCAR after the Talladega race and it makes me wonder if this is just a cooling time off for Earnhardt.
Further, Earnhardt's crash wasn't that hard, especially compared to other cars in the field and other crashes for Earnhardt.
Finally, why 2 weeks right off the bat?  Why not take it a week at a time and see how it goes?  If RG3 from the Washington Redskins gets a concussion on Sunday, he was already cleared mid-week to return to being a NFL for this week's game.
So, it's nice to see Regan Smith gets some good equipment to finally race in and A.J. Allingdinger will be back in racing as he will drive the 51 car for the next two weeks.
