When did Dale Earnhardt Jr have a bad wreck at Talladega in 2003?

I ask because I read this: Sadler's crash hardest recorded by NASCAR: #19-Elliott Sadler says NASCAR officials told him his head-on collision with the inside retaining wall at Pocono Racing on Sunday was the hardest recorded in the history of the sport.

Sadler's crash hardest recorded by NASCAR: #19-Elliott Sadler says NASCAR officials told him his head-on collision with the inside retaining wall at Pocono Racing on Sunday was the hardest recorded in the history of the sport. NASCAR did not give Sadler the number of G-forces recorded by the black box device and the governing body typically does not release that information. "We do not share those numbers except with the team and the folks at the Midwest Roadside Safety Facility at the University of Nebraska," NASCAR said in a statement. "They want to meet with me this weekend," Sadler said on Tuesday. "But we were told this morning that it was the hardest one they have in their data in history."That means harder than Kyle Petty's 2003 crash at Bristol which, according to published reports, was the hardest at the time at more than 80 Gs (80 times the force of gravity). Other hard hits that NASCAR publicly has claimed among the hardest include Dale Earnhardt Jr.'s 2003 crash at Talladega, David Reutimann's 2007 crash at California and Jeff Gordon's 2008 crash at Las Vegas.(ESPN.com)(8-4-2010)

Now I've looked it up, out of curiosity, and I don't remember that wreck, nor could I find it.
Update: Jr won the Spring race, finished 2nd in the fall race, and won the Busch race. Those were the only 3 talladega races in 2003, which is why it's got me perplexed.
Update 2: I read the comments on the original ESPN article, and the crash was at Dover.
