Hurricanes left wing Jeff Skinner retrieved the puck for Ryan after his goal.
"After I scored, coach [Bill Peters] said to me, 'How did that feel?'" Ryan said. "I said, 'It felt pretty good.'"
Ryan, who centered the fourth line alongside left wing Brock McGinn and right wing Chris Terry, went 12-7 on faceoffs (63 percent). His personal cheering section included his wife and son, who flew in from Charlotte, N.C., and his father and sister, who traveled from his hometown in Spokane, Wash.
"It's pretty unbelievable, no question," he said. "It was just an awesome day, an emotional day, playing my first NHL game and [to score a goal] was just icing on the cake. I can't really put it into words. We got the win and my emotions came over me.
"Obviously I'm super blessed and happy to be here."
Ryan was the oldest player to make his NHL debut with the Hurricanes; the previous oldest was forward David Gove, who was 27 years, 272 days old when he played his first NHL game Jan. 31, 2006. After his junior-hockey career, Ryan spent four seasons at the University of Alberta and then four seasons in Europe.
The Hurricanes signed him to a one-year, two-way contract June 16, 2015.
Charlotte was traveling back from two games against Manitoba in Winnipeg on Monday when Ryan learned he would have to grab a connecting flight to New Jersey to play Tuesday.
The trade that sent center Eric Staal to the New York Rangers on Sunday gave Ryan his NHL opportunity. He was asked after the game if he felt he was able to fill Staal's skates in his first NHL game.
"Did I replace Eric Staal?" he asked. "Lord, no. I don't think we're even in the same ballpark."
