Coach's Challenge: LAK @ CGY - 8:42 of First Period

At 8:42 of the first period in the Kings/Flames game, Calgary requested a Coach's Challenge to review whether Los Angeles' Tanner Pearson interfered with Calgary goaltender Brian Elliott prior to his goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed no goaltender interference infractions occurred before the puck crossed the goal line.

Therefore the original call stands - good goal Los Angeles Kings.
Since the Coach's Challenge did not result in the original call being overturned, the Calgary Flames forfeit their time-out.
