"The NHL is investigating whether human error or a glitch in the clock system at Staples Center was responsible for prolonging the Kings' game against the Columbus Blue Jackets on Wednesday long enough for Kings defenseman Drew Doughty to score the decisive goal in a 3-2 victory.

Colin Campbell, the league's senior vice president of hockey operations, said Thursday he believes the Blue Jackets were wronged because the clock was paused with 1.8 seconds left in the third period and Doughty's goal with 0.4 of a second left should not have been allowed. "In our opinion it was one full second," Campbell said of the stoppage."
