The incident occurred at 6:28 of the first period in Anaheim's 6-3 home win over Dallas on Sunday. Garbutt left the penalty box and skated at Penner before leaving his skates to deliver a check. He hit Penner in the head, and the Anaheim forward had to leave the game.
Penner didn't travel with the team for a road game in Toronto on Tuesday.
No penalty was called on the play.
Garbutt will forfeit US$14,743.60 in salary. He is eligible to return for the Stars' Nov. 3 game in Ottawa.
