Foyt driver Alex Tagliani suffers Indianapolis 500 qualifying crash

Polesitter for the 100th anniversary Indy 500 in 2011, Tagliani is likely to start at the back for the 100th edition of the race (the disparity in dates arising from the event being paused during world wars) after losing the rear of his AJ Foyt Racing Dallara-Honda out of Turn 4.

The car went into a slow slide as it headed toward the attenuator at the end of the pitwall.

As it spun around, the nose hit the attenuator before the car came to a stop on the frontstretch.

Tagliani was unhurt and the interruption to qualifying lasted only a quarter of an hour.

Max Chilton and Pippa Mann have now officially qualified for the race after their crashes on Saturday.

"We are definitely in the show," Ganassi driver Chilton said after posting a four-lap average of 226.686mph.

"Give credit to the guys. They built my car up from scratch in 12 hours last night.

"We had a few little problems with the balance but the team made a great car and fixed it in time. I can't thank them enough for that.

"On race day, we are going to be starting toward the back but we can come forward.

"I will get as many tips as possible from Dario Franchitti on how to get the car up to the front."

Andretti Autosport's Alexander Rossi, the last driver to get bumped out of the 'Fast Nine' on Saturday, was the fastest in the earlier practice session at 230.064mph.

Reigning IndyCar champion Scott Dixon had a scare in practice when an issue developed with his Chevrolet engine.

His Ganassi crew was able to install a new engine in the Gasoline Alley garage in one hour and 46 minutes.

Dixon is back in the technical inspection line to get ready for his qualification attempt.

Sunday's action is split into a two-hour qualifying session for the drivers fighting for 10th to 33rd positions, then a 45-minute pole shootout among the top nine from Saturday.
