Eric Stephens of the Orange County Register first reported terms of the deal.
Miller is one of the league's most experienced netminders as he prepares to play his 15th professional season. He spent the last three years with the Vancouver Canucks after spending more than a decade with the Buffalo Sabres, who drafted him in 1999, and a 19-game stint with the St. Louis Blues.
The 36-year-old Michigan State product ranks third among all active goalies in games played during the regular season at 709, per Hockey Reference.
Miller has seen his goals-against average jump above his career mark (2.61) over the past two campaigns to 2.70 and 2.80, respectively. That's more due to the Canucks' struggles than a sign of serious decline, however, as his save percentage has remained stable around .915.
While the word "retirement" has crept into the conversation in recent years, which is normal as a player heads toward his late 30s, the Michigan native has no plans to walk away in the immediate future.
In April, he told Ben Kuzma of the Province his body has continued to hold up and the competitive fire is still there, so he wanted to stay on the ice.
"I want to play until somebody kicks me out," Miller said. "You ask any guy who has retired, and I'm fortunate in that I've had three cousins who came before me in the NHL, and every single one of them told me: 'Go to the rink until they kick you out. Literally show up. Just go.'"
The veteran goaltender, who shined while helping lead the United States to a silver medal at the 2010 Winter Olympics, is also close to setting an American record.
Ryan Wolfe of the Hockey Writers provided the details:
So that gives Miller some added motivation heading into next season and potentially beyond.
All told, he ranked in the middle of the pack in save percentage among qualified goalies last season, and that's what to expect from him moving forward. He's no longer a player capable of helping carry a franchise on his shoulders, like he did in Buffalo, but he's still a solid asset.
Look for him to be a valuable veteran presence and backup to incumbent goalie John Gibson, giving the Ducks a good level of reliable goalkeeping depth.
