Ray Allen has announced he will remain retired and won't pursue opportunities to resume his NBA playing career.

Allen hasn't played since the 13-14 season with the Miami Heat.

Allen made the announcement on The Players Tribune in a letter to his 13-year-old self.

"I write this to you today as a 41-year-old man who is retiring from the game. I write to you as a man who is completely at peace with himself...

"Now, the most important question in your life isn’t, “Who am I supposed to be?” or even, “What do I have to do to win another championship?”

"It’s, “Daddy, guess what happened in math class today?”

"That’s the reward that awaits you at the end of your journey.

"Go to the court. Stay at the court.

"Get your work in, young fella.

"Most people will never really get to know the real you. But they’ll know your work."
