The Dallas Mavericks lost their third consecutive game on Wednesday night to the last-place team in the NBA’s Western Conference New Orleans Pelicans 119-116. The nature of the defeat is what drew attention, however.

The New Orleans Pelicans defeated the Dallas Mavericks on Wednesday night in a 119-116 nailbiter. The key moment of the game came in the final seconds of the fourth quarter when Mavs guard Spencer Dinwiddie, with his team trailing 117-116, got a layup opportunity in transition that would have given Dallas the lead.

The NBA acknowledged Thursday that officials erred at the end of the Pelicans-Mavericks game the previous night by not calling goaltending on what would have been a go-ahead bucket for Dallas.
