James Hinchcliffe is recovering in intensive care following surgery on his leg.
IndyCar series medical director Dr Michael Olinger said Hinchcliffe remains in a stable condition following his terrifying crash during practice for the Indianapolis 500.
It is believed that a piece of suspension pierced the upper left thigh of the Canadian driver.
Schmidt Peterson Motorsports team owner Sam Schmidt said: “Obviously we're relieved that James is awake and out of surgery.
“That's the most important thing on our minds right now and we will do absolutely everything required to ensure a complete recovery.”
Schmidt Peterson Motorsport is yet to discuss plans for the #5 Honda.
