IndyCar driver Justin Wilson is altering lives in death.

His younger brother said Tuesday on Twitter that Wilson saved six lives by donating his organs.

The 37-year-old Wilson died Monday night from a head injury suffered when a piece of debris struck him at Pocono Raceway. A British driver who lived in Colorado, Wilson was hit in the head during Sunday's race by piece of debris from another car. Wilson's car veered into an interior wall at the track and he was taken to a hospital in critical condition.

Wilson drove a Honda from 2008 through 2015 in IndyCar, and the manufacturer offered its condolences Monday.
