Manu Ginobili wrote a column detailing his decision to retire.
Ginobili plans on contributing to the San Antonio Spurs in retirement.
"I can't say this was a hasty or unexpected decision," Ginobili wrote. "I'm 41 years old. I've been stretching a little bit this basketball thing, right? In my head, last season was at all times 'the last one.' I never said it publicly because I didn't want to limit my options. I wanted to leave the door open for any changes in my mind or to see if I still felt the physical and mental strength needed to face a new season.
"I was sure to make it clear to [Spurs coach Gregg Popovich] this is not a 'goodbye, I'll see you,'" he added. "My kids have already started school, and while I'm in town, I'll be close to the team and the franchise. I can't help anymore by taking a charge or with a steal, but I'll try to contribute somehow. I appreciate all my teammates, the staff and all the people in the team. I want the best for the Spurs. If I can help, I will do it with pleasure."
