Officials in the NHL’s situation room will more closely observe the final minute of each period of each game and will refine the overall game-timing process as the result of the league’s investigation into a pause of the Staples Center clock during the Kings’ game against Columbus on Feb. 1. That hesitation added a second to the final period and allowed Drew Doughty score the winning goal.

Colin Campbell, the NHL’s senior vice president of hockey operations, said Thursday that the clock’s maker, Daktronics, had examined the clock and found “no defects.” He also said the off-ice crew working that game had been interviewed and that he was “completely satisfied” with the clock operator, whom he would not identify.
