At 16:19 of the third period in the Stars/Rangers game, Dallas requested a Coach's Challenge to review whether New York's Rick Nash interfered with Dallas goaltender Kari Lehtonen 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 New York Rangers.
Since the Coach's Challenge did not result in the original call being overturned, the Dallas Stars forfeit their time-out.
