The final 52ish seconds of a recent game between the Atlanta Hawks and the Miami Heat will be replayed. With that time remaining, and Atlanta up by 1 point, the scorer's table incorrectly reported that Shaquille O'Neal had fouled out.
http://sports.espn.go.com/nba/news/story?id=3192421 This hasn't happened since 1982. Strange that it can happen, but kinda cool. Presumably the teams will play again near to an actual scheduled match to mitigate the economic consequences.
To give you an idea of their threshhold for redoing a game, Indiana beat Dallas by six points this year in a game in which, around midgame, a Pacer was credited with a three-point shot when in fact he only made a two-point shot. They determined that there wasn't enough chance that the misscore affected the outcome to take further action.
