SONOMA - Driver Will Power of Team Penske broke two vertebrae in his lower back and sustained a concussion Saturday after crashing into Nelson Philippe of Conquest Racing during a practice session for the Indy Grand Prix of Sonoma.

Philippe also sustained a concussion along with an open fracture to his left foot that required surgery.

The 28-year-old Power, the former road course specialist who finished fifth in this year's Indianapolis 500, crashed into Philippe coming out of a blind corner at Infineon Raceway. IndyCar officials didn't expect any further updates on his status until today.

Power, Penske's third driver, was airlifted to nearby Santa Rosa Memorial Hospital. Philippe was taken by ambulance to the same hospital, where he had surgery on his foot.

IndyCar officials said both drivers were reported to be awake and alert and would be hospitalized at least overnight. They each withdrew from the race, which means no new driver will fill the seat.

Philippe lost control at the top of the hill on Turn 3A, and the front end of his car was initially clipped by E.J. Viso. Power arrived moments later and couldn't avoid an ugly crash.

"It's pretty serious," said Power's Penske teammate Ryan Briscoe, who qualified second Saturday. "We definitely need to look at the safety over here and what can be done differently with spotting or whatever to Turn 3A. It's a dangerous corner. So, definitely wishing him the best at the moment."

Power was 16th on the season points list with 209.

Dario Franchitti, who won the pole Saturday, called it a "horrible accident."

Philippe, a Frenchman, is an IndyCar rookie.

Doctors have access to a computerized test called "ImPACT" on site that can help them determine the severity of the concussions. The test was developed by the Sports Concussion Program at the University of Pittsburgh Medical Center. It puts the brain to work and derives data about points of trauma - measuring attention, memory, processing speed and reaction time.

Formula One

VALENCIA, Spain - Lewis Hamilton took the pole position for the European Grand Prix on Saturday to lead a McLaren 1-2 in qualifying.

Hamilton had a best lap of 1 minute, 39.498 seconds around the Valencia street circuit to give the defending Formula One champion his first pole of the season. Teammate Heikki Kovalainen will start today's race from second spot.

"Clearly, we have very, very good pace this weekend," said Hamilton, who is coming off his first win of the season at the Hungarian GP. "We thought we would be competitive, but I don't think we thought we'd be on the front row."

Brawn GP's Rubens Barrichello will start third ahead of Red Bull's Sebastian Vettel and overall leader Jenson Button.

Luca Badoer, who is replacing the injured Felipe Massa for Ferrari, qualified last on the 20-car grid on his return to Formula One after a 10-year absence.

Kovalainen was poised to give Hamilton a run for pole but slid out as he came out of the penultimate turn to give Hamilton his 14th career pole and McLaren's first 1-2 start since last year's Hungarian GP.
