The opening minutes of Game 1 of the Eastern Conference finals between the Pittsburgh Penguins and Tampa Bay Lightning featured scary moments for both teams.

Pittsburgh defenseman Kris Letang left briefly early in the first period after getting hit illegally from behind by Tampa Bay's Ryan Callahan. Later, Tampa Bay goaltender Ben Bishop exited with an apparent left leg injury and was replaced by backup Andrei Vasilevskiy.

Callahan earned a 5-minute major penalty after crunching Letang in the corner by the Pittsburgh net. Letang made it off the ice under his own power and returned later in the period.

Bishop, a Vezina Trophy finalist, was attempting to move from the side of the net back in front during a scramble and appeared to wrench his left leg. He left the ice on a stretcher.
