Coyotes GM John Chayka watched as goalie Antti Raanta stopped pucks on the ice, which was a rare sight this season: a key acquisition in the offseason, Raanta has played about 90 minutes through nine games because of injury.

Arizona is 0-8-1, at the very bottom of the NHL standings. This is despite a handful of high-profile moves from Chayka in the offseason -- getting Raanta and center Derek Stepan from the Rangers, defenseman Niklas Hjalmarsson from the Blackhawks and snagging head coach Rick Tocchet from the Stanley Cup champion Penguins' staff.

Under Chayka, the 28-year-old wunderkind, the Coyotes are 30-50-11 through Wednesday night.

"We're in a rut as an organization -- not these [nine] games, but for five or six years," he said.

Wild forward Zach Parise underwent back surgery Tuesday and will be out eight to 10 weeks, general manager Chuck Fletcher announced.

The 33-year-old has practiced some but hasn't played in a game this season because of back issues. Parise had a microdiscectomy procedure, which is a minimally invasive surgery to relieve pressure on a lumbar herniated disk.

The Panthers have claimed Antti Niemi off waivers to shore up their goaltending position, with starter Roberto Luongo sidelined because of an injury to his right hand.

Niemi was claimed on Tuesday, a day after being waived by the Penguins. He allowed 16 goals in losing three games for the Penguins. Niemi is now on his third team in four months and fourth since winning the 2010 Stanley Cup with Chicago.

The Maple Leafs announced today that the club has agreed to terms with defenceman Roman Polak to a one-year contract worth $1.1M.

Polak, 31, has registered 23 goals and 92 assists in 634 career NHL games with the Maple Leafs, Sharks and Blues. In 2016-17, he collected 11 points (four goals, seven assists) in 75 regular season games with Toronto while also skating in two playoff games.

The Ostrava, Czech Republic native was originally selected by St. Louis in the sixth round (180th overall) of the 2004 NHL Draft.

The Penguins have acquired forward Riley Sheahan and a 2018 fifth-round draft pick from the Red Wings in exchange for forward Scott Wilson and a 2018 third-round draft pick.

The 25-year-old Sheahan, whose contract expires at the end of this season, has no points in eight games this year. Sheahan has 38 goals and 60 assists in 292 career games with Detroit. He was the Red Wings' first-round draft pick in 2010.

Edmonton Oilers forward Leon Draisaitl was placed on injured reserve Monday as he deals with an eye injury that is creating concussion symptoms.

"He had an eye injury," coach Todd McLellan said Saturday. "The eye was swollen shut. Obviously, the eye is attached to the head, which leads to concussion-type symptoms now."

Ottawa defenseman Erik Karlsson will make his season debut when the Senators host the Vancouver Canucks on Tuesday night.

Senators coach Guy Boucher confirmed his captain's return to the lineup at Monday's practice.

Karlsson missed Ottawa's first five games of the season after undergoing offseason surgery to fix tendons in his left foot.

The Vegas Golden Knights placed goaltender Marc-Andre Fleury and forward Jonathan Marchessault on injured reserve Sunday, general manager George McPhee announced.

Fleury took a knee to the head in Friday's loss to the Red Wings. The NHL didn't think the hit was severe enough to take him off the ice as part of its concussion protocol, but Fleury has a history of concussions.

Marchessault suffered a lower-body injury Friday. Both players are expected to miss at least a week.

A person with direct knowledge of the situation says defenseman Mark Streit will not report to the minors after clearing waivers and will spend the next few days weighing his options.

The person spoke to The Associated Press on condition of anonymity because talks between Streit and the Montreal Canadiens have been private.

Before the Vegas Golden Knights took the ice in their inaugural home game on Tuesday night, the team introduced first responders in an emotional 15-minute ceremony. Doctors, nurses, policemen and firefighters were called out by name, accompanied by Golden Knights players.

There also was a 58-second moment of silence to honor the 58 people killed in the worst mass shooting in American history, which occurred Oct. 1 at a country music concert in Las Vegas -- less than a mile from T-Mobile Arena, home of the Golden Knights. The names of the victims were emblazoned on the ice.

The Golden Knights beat the Coyotes 5-2 to become the first expansion team to start 3-0.
