Watch: Trocheck scores controversial goal, extends shootout vs. Lightning

Well, that was weird.

In need of a goal to extend Tuesday night's shootout between the Florida Panthers and Tampa Bay Lightning, forward Vincent Trocheck provided a rather head-scratching moment.

After losing control during his deke, referees deemed the play was dead, as NHL rules state the puck cannot travel backwards during a shootout attempt.

Upon review, it was determined the puck only traveled sideways, and Trocheck was awarded the goal.

Five shooters later, Tampa Bay ultimately went on to win the shootout, and the game 4-3.
