At 13:02 of the second period in the Flames/Ducks game, Calgary requested a Coach's Challenge to review whether Anaheim was off-side prior to Kevin Bieksa's goal.

After NHL Hockey Operations staff reviewed all available replays and consulted with the linesmen, the call on the ice was upheld - good goal Anaheim Ducks.
Since the Coach's Challenge did not result in the original call being overturned, the Calgary Flames forfeit their time-out.
