Instant replay first came to NBA in the 2002–03 season. In Game 4 of the 2002 Western Conference Finals, Los Angeles Lakers forward Samaki Walker made a three-point field goal from the half court at the end of the second quarter. However, the replay showed that Walker's shot was late and that the ball was still in his hand when the clock expired. The use of instant replay was instituted afterward.
