Steven Stamkos had a natural hat trick and the Tampa Bay Lightning beat Toronto 5-3 Wednesday night in a game that included a frightening injury to Maple Leafs defenseman Paul Ranger.

Ranger left the ice on a stretcher after his head hit the boards following a first-period hit from Alex Killorn. He was "stable, conscious and alert," according to the Maple Leafs, after being taken to the hospital for what the team called a "precautionary assessment."

Toronto announced the update on Ranger's condition on its Twitter account.

James Reimer gave up a goal on the first shot he faced, and the Maple Leafs lost their third straight.
