At 16:15 of the first period, with the score 2-1 in favour of the Predators, Michael McCarron and Tom Wilson dropped the gloves in a big beefy brute tilt.
After the tilt the game remained 2-1 until 15:59 of the second period when Alex Ovechkin tied the game at two. It remained 2-2 until a minute left in the third period when Alex Ovechkind scored the go-ahead goal. However, that goal was overturned based on "interference with the goaltenders ability to stop the puck", so the goal was overturned.
It was a play that is often called a goal or not a goal, it just appears to depend on the mood of the referees or the situation room in Toronto. No other goals were scored in the game, and it went to the shootout where the Predators won the game.
