NBA: Spurs guard Stephon Castle exits game with pelvis injury

San Antonio Spurs guard Stephon Castle will miss Tuesday's road game against the Los Angeles Lakers after sustaining a second-quarter pelvis injury.

Castle fell on his tailbone while attempting to block a fast-break dunk by Lakers forward Rui Hachimura with just over four minutes left in the first half. He left the game for the locker room and was ruled out after halftime.

The Spurs confirmed that X-rays were negative, and Castle was diagnosed with a pelvis contusion.

Before leaving the game, the 21-year-old Castle had contributed two points and seven assists in 12 minutes, helping San Antonio build an 84-55 halftime lead over the short-handed Lakers.

Last season's NBA Rookie of the Year is averaging 17.1 points and 7.0 assists across 42 games (41 starts) this season. Over his two NBA seasons, Castle has posted averages of 15.5 points and 5.1 assists in 123 games (88 starts).
