Hamhuis left early in the third period after his head bounced hard off the end glass following a shoulder hit by the Ducks captain. Hamhuis lay flat on the ice for several minutes before being helped to the dressing room. Hamhuis' condition should be updated further later Thursday by the Canucks.
The NHL's hockey operations staff in Toronto took a look at the hit Wednesday night but a source said it deemed the hit legal so Getzlaf won't face any further discipline.
"I don't want to hurt anybody out there," said Getzlaf, who also had an assist in the Ducks' 4-3 victory, his first game back after missing six weeks because of nasal sinus fractures. "I didn't leave my feet, I kept my shoulder down and he was just following through on a pass. It was an unfortunate accident. He turned as he made his pass and he was well aware that I was coming."
Canucks coach Alain Vigneault said Hamhuis seemed fine in the locker room after the game but insisted he didn't see the hit and wouldn't comment on it.
"Dan has the glass plastered to his face right now," he said. "This is a physical game, a big man hitting a defenseman, it's part of the game."
