<P> 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 . </P>
