Jack Eichel had disk replacement surgery on his neck Friday.
It is unknown when the center will be able to play for the Vegas Golden Knights, who traded for him this month and approved the surgery he preferred.
"Jack Eichel underwent disk replacement surgery today that his doctor described as successful and without complications," the Golden Knights said in a statement. "He is expected to make a full recovery. We will provide additional updates on the anticipated timing of his return to the ice when appropriate."
