"He had his mother's class ring on and he caught it on a nail," explained his father, Gerald Sr.
Gerald was attempting to dunk on a Nerf-type hoop in his bedroom.
"They couldn't reattach it," said Gerald Sr. "They had to shave it. That was a long night. It was just a tragic time."
Young Gerald now expertly hides that ring finger on his right hand. He had to get used to playing without the tip of his finger on his shooting hand.
That may be one reason why early in his career Gerald couldn't even make the team. He was cut altogether as a freshman at Dobie High in Houston and the next year was a mid-season addition to the sophomore team.
Mr. Green was hesitant to go into much details.
When asked if the finger injury was the reason his son was cut, he said, "I'll let you put that together. ... It's just the way people perceive you."
