(PHOENIX, AZ) -- Jeff Gordon had one of the hardest crash impacts of his career in Sunday's UAW-Dodge 400. He was sore on Monday, but that didn't stop him from testing at Phoenix International Raceway. "I felt like I was doing crunches all day 'cause my stomach muscles were really sore," said Gordon.

After his crash on Sunday he told NASCAR President Mike Helton the section of wall he hit at Las Vega Motor Speedway was not a "soft wall" like much of the other portions of the wall at LVMS. He told Helton this wall section should be fixed. "It's an unfortunate situation, but I hope that something good can come out of this situation where we recognize that those areas need to have soft walls." Apparently the isolated area of the wall Gordon hit is designed to allow the entry and exit of emergency crews and it is not a "soft wall."

Officials at LVMS have indicated to Gordon that they intend to take a look at the issue. "We'll be pretty upset if we go back there again and they haven't fixed it."

Gordon said on Monday he was just lucky that some of the impact of his Sunday crash was absorbed by hitting the wall at an angle. "I want to make sure that no matter what angle you hit it at, you can walk away."
