Tampa Bay Lightning goalie Ben Bishop was injured just two minutes into their game on Thursday night when he came diving out of his net in an effort to play the puck and was accidentally kneed in the back of his head by teammate Nikita Kucherov.
The Senators ended up scoring on the play as Bishop remained on the ice. He had to be helped off the ice by trainers and teammates.
Bishop has been one of the biggest surprises in the NHL this season and is an early leader for the Vezina Trophy which is awarded annually to the top goalie in the league. He entered play on Thursday with a .933 save percentage, which was good enough for second best in the league, trailing only Edmonton's Ben Scrivens.
Bishop has also been one of the biggest reasons Tampa Bay has remained near the top of the Atlantic Division and comfortably in a playoff spot in the absence of star forward Steven Stamkos.
