Penner has full mobility and is walking under his own power, according to the Ducks, who won their seventh in a row in a 6-3 victory.
Penner had just passed the puck in the Dallas end during a Ducks power play when Garbutt hit him up high with his shoulder at 5:29 of the second. The 6-foot-4, 247-pound Penner laid prone before teammates helped him off the ice to the dressing room.
Penner entered Sunday's action with two goals, two assists and a plus-7 rating in five games and re-assumed his top line spot in his second stint with the Ducks.
Asked about Penner, Anaheim coach Bruce Boudreau said, "We'll see. It looks [OK] right now, but there's a big series of tests you have to go through when you're knocked out on the ice."
