Per USA Today's Mike Brehm:

Anaheim Ducks star Teemu Selanne's ever-present smile will have a different look.

The team tweeted that Selanne lost several teeth and has a swollen jaw after he was hit by an errant high stick from Philadelphia Flyers defenseman Luke Schenn early in the third period.

Selanne, 43, who has announced this will be his last season, didn't return to the game. He's considered day-to-day. The Ducks have three games left in an eight-game swing that would be the last time for some Eastern Conference fans to see Selanne.

Schenn wasn't called for a penalty. His stick came up after a collision with Ducks defenseman Bryan Allen.
