At 12:23 of the second period in the Red Wings/Flames game, Detroit requested a Coach's Challenge to review whether Matthew Tkachuk interfered with Red Wings goaltender Petr Mrazek prior to his goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that no goaltender interference infractions occurred.

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