At 12:34 of the first period in the Jets/Predators game, Winnipeg requested a Coach's Challenge to review whether Nashville was off-side prior to Austin Watson's goal.
After reviewing all available replays and consulting with the linesman, NHL Hockey Operations staff confirmed that the Predators entered the attacking zone legally prior to the goal.

Therefore the original call stands - good goal Nashville Predators.
Since the Coach's Challenge did not result in the original call being overturned, the Winnipeg Jets forfeit their time-out.
