Katherine Legge will make a late attempt to qualify the third Schmidt Peterson Motorsport entry for this year's Indianapolis 500.
The Briton split with IndyCar team Dragon Racing at the end of 2012.
She sat out the first part of the year before racing the DeltaWing in the latest American Le Mans Series event at Laguna Seca a week ago.
Legge will attempt to join the field in Schmidt's #81 car, which originally joined the entry list as #99.
Her entry becomes the 34th scheduled to attempt to make the 33-car field, meaning that at least one car will be cut on Bump Day on Sunday
