MORNING ROUNDUP

• Brad Marchand, David Backes and David Krejci each scored a power-play goal, and Tuukka Rask stopped 26 shots to lead the Boston Bruins to a 5-1 victory over the Toronto Maple Leafs on Thursday night in Game 1 of their first-round Eastern Conference playoff series.

David Pastrnak also scored for Boston, and Sean Kuraly bunted one out of the air and into the net over goalie Frederik Andersen to make it 4-1 with seven minutes gone in the third period.

Krejci bounced it in off Andersen from behind to make it 5-1 after Toronto's Nazem Kadri was thrown out of the game and given a fiveminute major for an elbow to Tommy Wingels' head. Zach Hyman scored Toronto's only goal, and Andersen made 35 saves.

• Brett Favre says he might have had "thousands" of concussions during his Hall of Fame career.

The three-time NFL MVP who played from 1992-2010 and was known for his aggressive approach to football said Thursday on NBC's "Megyn Kelly Today" that he is experiencing short-term memory issues.

Favre, 48, has become an advocate for concussion research and said he had three or four known concussions during his lengthy career, which spanned 302 regular-season games and 24 in the postseason.

"But as we're learning about concussions," he told Kelly, "there's a term we use in football and maybe other sports, that I got 'dinged.' When you have ringing of the ears, seeing stars, that is a concussion.

"If that's a concussion, then I've had hundreds, probably thousands, throughout my career, which is frightening."

Favre added that he worries about developing chronic traumatic encephalopathy (CTE) as he ages.
