Lightning's Ben Bishop exits on stretcher with left leg injury

— -- PITTSBURGH, Pa. -- Tampa Bay Lightning netminder Ben Bishop left Game 1 of the Eastern Conference Finals on a stretcher in the first period after suffering an injury to his left leg.

With 7:35 left in a scoreless first period, Bishop, a finalist for the Vezina Trophy as the league's top goaltender, was scrambling around the Tampa Bay net during a Pittsburgh Penguins forecheck and seemed to tweak his left side or knee as he fell to the ice. Bishop immediately grabbed at his left knee.

It did not appear from replays as though any other players came in contact with him.

Trainers attended to Bishop, and even though he sat up, team trainers called for a stretcher, and he was taken from the ice. Bishop, 29, was replaced by backup Andrei Vasilevskiy.

Earlier in the first period, Tampa Bay forward Ryan Callahan was given a five-minute major penalty for driving Pittsburgh defenseman Kris Letang head-first into the boards.

Letang left the ice but returned to the bench during the injury timeout when Bishop was being attended to. Callahan remained in the game but is likely to face supplemental discipline from the league's Department of Player Safety for the hit.

Lightning center Tyler Johnson went down later in the first period on a hit into the boards. He appeared to suffer a lower body injury and had to be helped off the ice.
