Hendrick cars allowed back on track at Infineon

SONOMA, Calif. -- Jeff Gordon and Jimmie Johnson, who were not allowed to participate in any on-track activities on Friday after their cars failed initial inspections, were first on the track for practice Saturday morning at Infineon Raceway.

NASCAR cleared both cars for Sunday's race at the 1.99-mile road course.

Gordon and Johnson were parked on Friday after officials discovered the front right fenders were flared out beyond the wheel well on both cars.

Both teams will face major penalties for the infraction when NASCAR reviews the case early next week.

It is the second violation involving the Car of Tomorrow, which is being used in 16 races this season.

Crew chief Tony Eury Jr. was suspended for six races and fined $100,000, and driver Dale Earnhardt Jr. was docked 100 championship points after alterations to the rear-wing bracket were discovered at Darlington.

Gordon and Johnson can afford a heavy hit. Gordon, who became a first-time father on Wednesday, leads the points standings by 264 over second-place Denny Hamlin.

Johnson, the defending Cup champion, is third -- 337 points behind Gordon. He is 11 points ahead of fourth-place Matt Kenseth and 136 ahead of Jeff Burton in fifth.

Johnson and Gordon will start 41st and 42nd in the 43-car lineup
for Sunday's Toyota/Save Mart 350.

In the morning practice, with cooler track temperatures and fast
speeds, Gordon was third fastest and Johnson 16th. In the
afternoon, Johnson was ninth and Gordon, who spun harmlessly at one
point, wound up 10th.

Gordon, a five-time winner and the defending champion at Sonoma,
said it's going to be tough to try to drive to the front on the
treacherous road circuit that winds through the hills of Northern
California wine country.

"We're really put into a bind here and we're going to do our
best, that's all I can say," Gordon said. "You know we're going to do all we can to make the car as
fast as it can be and to try to come up through that field the best
way, smoothest way possible while trying to stay out of trouble and
trying to play the right pit strategy.

"We'll try to do everything in our power to get the best finish
out here we can. I'll be honest, right now it's a little hard for
us to be realistic about a win. It's more about being realistic
about trying to get a top 10."
