His family sent a statement to the NBA on Thursday: "NBA Ambassador and 13-year NBA veteran Jason Collins is currently undergoing treatment for a brain tumor. Jason and his family welcome your support and prayers and kindly ask for privacy as they dedicate their attention to Jason's health and well-being." #nbaplayer #jasoncollins #brooklynnets #gay #braintumour
