The NBA admitted on Tuesday that Chauncey Billups' three-pointer at the end of the third quarter against the Magic on Monday night should not have counted,  according to the Associated Press.

The referees weren't allowed to review the replay in order to make a better call during Game One, a rule that could be changed this summer.

"After reviewing the video of last night's Pistons-Magic game, we determined that the play that concluded with Chauncey Billups' 3-point field goal at the end of the third quarter took approximately 5.7 seconds," League President Joel Litvin said in a statement. "Because there were only 5.1 seconds remaining in the quarter when the play began, the shot would not have counted had the clock continued to run."

The NBA said that the timekeeper for the game was from a neutral city, standard procedure under the league's rules.

"The referees followed proper procedure in addressing the clock malfunction by estimating the elapsed time and using their judgment as to whether the shot was taken in time," Litvin said. "Under NBA rules, the referees did not have the option of using instant replay and a timing device to determine exactly how much time had elapsed, nor do the rules allow for a re-play after a clock malfunction is discovered."
