It was a crazy 20 minutes inside the Saddledome on Friday night.

The Boston Bruins and Calgary Flames combined for four goals in the first 3:23 of the game, with the two sides ultimately scoring three goals apiece by the conclusion of the first period.

Mikael Backlund got the hosts on the board first just 20 seconds after the opening puck drop.

And just over two minutes later, Backlund struck again to double Calgary’s advantage.

But a mere 24 seconds later, Patrice Bergeron got the Bruins on the board.

However, Boston’s excitement was short-lived. Johnny Gaudreau potted a the Flames’ third goal just 25 seconds after Bergeron scored.

After nearly three minutes without a goal (felt like an eternity), Bergeron buried his second goal of the night.

Then at 12:20, a pretty pass from Karson Kuhlman got Charlie Coyle on a breakaway, and he tied the game up.

What a period.
