Changes made to Indy 500 qualifications after Ed Carpenter crashes during practice

A scary incident took place during practice for the Indianapolis 500 on Sunday, as Ed Carpenter's car spun into the Turn 2 wall and flipped over before returning to its side.

"It caught me by surprise," Carpenter said. "I wasn't expecting to swap ends. The car was actually feeling pretty good, better than it did yesterday. Things are a little unpredictable right now."

The crash, which forced practice to be delayed for repairs to the track and safety fence, added to growing concerns over the safety of the new superspeedway aero kits. Carpenter's CFH teammate, Josef Newgarden, lost control, hit the wall, and flipped his car on Thursday, while Helio Castroneves went airborne in an earlier crash.

"As a precautionary measure, IndyCar will require that the cars qualify today in the same aero setup that they will run in the Indianapolis 500 next weekend," said Mark Miles, the CEO of Hulman & Company - the parent company for IndyCar - in a statement after Carpenter's crash. "Also, for today, boost levels will return to race conditions. Given these changes, we have elected to not award points for today's qualifications."

Qualifying will now take place at 3:15 p.m. ET on Sunday, with Carpenter, who was checked and released from the track's medical center after the crash, attempting to become the first driver to win three consecutive Indy 500 poles.
