Kyle Busch's 11-year-old son takes big step in racing world nearly two weeks after his dad's stunning death

Brexton Busch, the 11-year-old son of NASCAR legend Kyle Busch, returned to the racetrack Tuesday for the first time since his dad's death nearly two weeks ago.

Busch ran practice laps at Charlotte Motor Speedway ahead of the CookOut Summer Shootout, a Legend Car Series race. Kyle Busch, 41, died unexpectedly late last month after a battle with pneumonia turned into sepsis.

A private memorial was held for Busch on Tuesday afternoon. The family announced that a public memorial would take place later this year.
