Duncan is being held out due to soreness in his right knee. The matchup between the Spurs and Warriors is highly anticipated being the first meeting between the top two teams in the NBA.
Spurs coach Gregg Popovich has a history of resting star players for big games during the regular season. Popovich was fined by the NBA in November 2012 for resting four players for a nationally televised game against the Miami Heat.
Popovich sent Duncan, Manu Ginobili, Tony Parker and Danny Green back to San Antonio before the game in a Miami, a game which the Spurs almost won.
Warriors coach Steve Kerr, a former Spurs teammate of Duncan, had an interesting take on his absence.
Duncan, now in his 19th season, is averaging 8.9 points, 7.5 rebounds and 1.3 blocks per game.
