The 46-year-old withdrew from the Zurich Classic in New Orleans to be with wife, Jackie, and Jacob before later releasing a statement through the Tour saying he did not know when he would return.

“Our son is undertaking the biggest challenge of his life thus far,” Senden said in the statement. “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. We are grateful for the outpouring of love we have experienced and ask that you keep Jacob in your prayers and hearts.

“With respect, we now ask for privacy in this matter.”
