Grosjean crashes out of Indy 500

Romain Grosjean crashed out of the 107th Indy 500 to trigger the second caution of the race.

The former Haas F1 driver was competing in his second Indy 500 having retired from last year's event in similar circumstances.

The Frenchman had been set back by a collision with Andretti Autosport teammate Colton Herta in the pit lane on lap 135 which earned the American a pass-through penalty.

But with 50 laps to go, Grosjean ran shallow through Turn 2 and was affected by aero wake from Christian Lundgaard's RLL Honda in front of him, sending his car spearing up into the wall.

It is the second crash for Grosjean in his last two oval races having also retired from a race at Texas Motor Speedway earlier this year.

His incident followed rookie Sting Ray Robb's earlier crash at Turn 1 when in battle with Graham Rahal.
