Selanne, 39, was struck in the face by a deflected puck with 8:29 remaining in Wednesday's 4-3 win over the Boston Bruins. The puck, shot by teammate Ryan Whitney, was deflected by the Bruins' Miroslav Satan and bounced off the ice before striking Selanne in the face.
"That is unfortunate for Teemu," Anaheim Coach Randy Carlyle said. "We all know how much he loves to play the game. Why does it happen to one player over another? I don't know how to explain it."
Selanne, a first-round draft pick in 1988 by the Winnipeg Jets, was playing in his third game this season after missing 17 contests with a fractured left hand.
He has scored 23 points -- 16 goals and seven assists -- in 30 games.
