Watch: Lightning denied 2 quick goals on reviews

Lightning didn't strike twice - or even once - in the second period Monday night, as Tampa Bay had a pair of goals disallowed upon review in Game 4 against the Florida Panthers.

Bolts forward Alex Killorn thought he opened the scoring, but his marker was called back after the officials and the situation room in Toronto examined the play for over 10 minutes.

"After a thorough examination of all available replays, video review determined the puck hit the protective netting in the Florida zone and went out of bounds at 11:22 (8:38 elapsed time) prior to Alex Killorn's goal," the NHL said in its official explanation.

"The decision was made in accordance to Rule 85, which states in part, 'When a puck goes outside the playing area at either end or either side of the rink, strikes any obstacles above the playing surface other than the boards or glass, causes the glass, lighting, timing device, or the supports to break, it shall be faced off at the nearest faceoff spot in the zone from where it was shot or deflected out of play.'"

Shortly thereafter, the Lightning again thought they'd tallied. However, forward Anthony Cirelli won the faceoff with his hand before Nikita Kucherov scored, wiping that one out as well.

"The situation room determined that Anthony Cirelli directed the puck to Nikita Kucherov with a hand pass at 9:29 of the second period (10:31 elapsed time) - one second prior to Kucherov's goal," the league said. "The decision was made in accordance with Rule 79."

The Lightning swept the Panthers out of the second round of the playoffs and advanced to the Eastern Conference Final with a 2-0 victory.
