Golden State Warriors forward David West announced his retirement on Thursday, one day after celebrating his 38th birthday.

The two-time All-Star posted a message on Twitter:

"We are but a collection of our experiences I have been fortunate enough to live out my childhood dream of playing in the NBA. After 15 seasons I have decided to retire from the game of basketball. I am humbled and thankful for the support of my family, friends, coaches, teammates, organizations and fans throughout this experience. To anyone who has ever cheered me on, been in my corner, prayed or simply said a nice word on my behalf, I am grateful. Belief in yourself is non-negotiable."
