IndyCar driver Stefan Wilson shared a video of himself walking on Saturday.

While Wilson was wearing a brace, he was shown getting out of a hospital bed and taking a few steps before saying “I’m back.”

Wilson had qualified one of the two Dreyer & Reinbold Racing/Cusick Motorsports Chevrolet entries 25th for the 107th running of the Indianapolis 500. On Monday during a practice session Wilson was hit from behind by the car driven by Katherine Legge.

As a result of the crash Wilson fractured the 12th thoracic vertebrae and was declared unable to race.

Graham Rahal will now drive the No. 24 car in the race.
