Report: Spurs to sign Duncan to three-year deal

The San Antonio Spurs and forward Tim Duncan are finalizing the details on a three-year contract, according to Yahoo! Sports.

After losing to the Oklahoma City Thunder in the Western Conference finals, Duncan was set to become a free agent. Despite the attention that a veteran forward like Duncan could draw on the open market, he stated that he was a "Spur for life." 

Duncan, who was drafted by the Spurs in 1997, has spent his entire 15-year career in San Antonio. At 36 years old, a three-year contract will likely ensure that Duncan finished his career with the team that drafted him.

There is no word on the details of Duncan's contract, but he is expected to get a similar deal to the one the Boston Celtics gave 36-year-old Kevin Garnett (three-year, $34 million).

Duncan averaged 15.4 points, 9.0 rebounds and 2.3 assists per game this past season.
