"As a family, we appreciate the support and kindness that everyone has offered us at this difficult time. Together, we will stand strong to tackle this disease and look forward to the day when Jacob is cancer free."

Jacob, 13, is the only child of Senden and his wife Jackie.

The family live primarily in north Texas.

Senden won the 2006 John Deere Classic and the 2014 Valspar Championship on the PGA Tour.

He also claimed the 2006 Australian Open in his homeland and has long been regarded as one of the best drivers in the game.
