BOSTON -- Boston Bruins defenseman Dennis Seidenberg was injured on the first shift of the game Monday night in Game 7 of the Eastern Conference Quarterfinals against the Toronto Maple Leafs at TD Garden.

Seidenberg appeared to hit leg on leg against Maple Leafs forward Matt Frattin about 31 seconds into the game after a pinch down the left wall.

Officially, Seidenberg took one more shift in the first period for six seconds, but did not return to the ice. He was still sitting on the bench as of the second period.
