Pedrie Wannenburg, a former South Africa rugby player, died after his car was struck by a teenage driver who was fleeing from police outside Houston. He was 41.
South Africa Rugby announced Wannenburg's death on Saturday and said he "represented his country with aplomb" during his 20 test matches with the Springboks from 2002-07.
Wannenburg was pronounced dead after being flown to an area hospital on Friday evening, the Harris County sheriff's office said. His 8-year-old son was also hospitalised with life-threatening injuries, Sheriff Ed Gonzalez said early on Saturday.
The 16-year-old driver of the car that struck Wannenburg's vehicle and two others have been charged with felony murder, reckless aggravated assault-serious bodily injury, and three counts of aggravated assault-bodily injury, Gonzalez said on Twitter. The teenager's name was not released.
