Penner's deal was announced Sunday with the Stanley Cup champion Kings, who have retained every significant player from last season's run to their first NHL championship.
Penner is a two-time Stanley Cup champion who has been with the Kings since midway through the 2010-11 season. He struggled during the regular season last winter, managing just seven goals and 10 assists in 65 games, but emerged as a big contributor in the postseason on a line with Mike Richards and Jeff Carter.
Penner scored the series-winning overtime goal in the Western Conference finals against the Phoenix Coyotes, sending Los Angeles to just the second Stanley Cup finals in franchise history.
The 6-foot-4, 245-pound Penner has 135 goals and 262 points in 489 career games with three teams.
Lightning, Salo reach 2-year, $7.5M deal
Over portions of 13 NHL seasons, Salo has 93 goals and 305 points. He appeared in 100 playoff games with the Senators and Canucks. He also has been a part of three teams that competed for Finland in the Olympics.
Salo, a ninth-round draft pick of the Senators in 1996, appeared in 69 games with Vancouver last season, finishing with nine goals and 25 points. He led Canucks defensemen with seven power-play goals.
Tampa Bay also signed draft-day acquisition Benoit Pouliot to a one-year deal worth a reported $1.8 million.
Pouliot, who played in 74 games with the Boston Bruins last season, scored a career-high 16 goals and 32 points in 2011-12. Boston traded his rights to Tampa Bay on June 23 in exchange for forward Michel Ouellet and a fifth-round pick.
Source: Habs give Prust $10M deal
Prust played a key role on New York's checking line and penalty killing units. Rangers coach John Tortorella praised him after the season and general manager Glen Sather expressed an interest in retaining the 28-year-old winger, but the sides reached an impasse in contract talks.
Prust made $800,000 last season. In 279 career games, he has 24 goals, 63 points and 612 penalty minutes.
The veteran forward signed a $1 million, one-year deal with the Habs on Sunday. He'll earn a total of $2 million next season -- half paid by Montreal, half paid by Toronto.
Armstrong's two seasons in Toronto were hampered by injuries. The 29-year-old appeared in just 29 games last season, scoring one goal and three points.
Mason returning to Preds
The deal also has $250,000 in potential bonuses.
Mason returns to the Predators where he spent eight seasons from 1998-2002 and 2003-08. He posted a 58-43-12 record with a 2.61 goals-against average a .913 save percentage in 135 games with the Predators.
He has also played two seasons for St. Louis (2008-10) and two seasons for Atlanta-Winnipeg (2010-12). He was 8-7-1 with a 2.59 GAA and a .898 save percentage and a pair of shutouts in 20 games for the Jets last season.
The Predators also have agreed to terms with forward Brian McGrattan on a one-year contract worth $600,000.
Wings add Tootoo, Gustavsson, Samuelsson
The Nashville Predators drafted Tootoo in 2001 and the tough guy has spent his entire career with them, racking up 725 career penalty minutes and 125 points.
Gustavsson played for Toronto last season and won a team-high 17 games with a team-low 2.92 goals-against average. He was 39-45 with a 2.98 GAA over three seasons with the Maple Leafs. The 27-year-old Swede will be Jimmy Howard's backup in Detroit. Ty Conklin and Joey MacDonald split time as No. 2 goalies for the Red Wings last season.
Samuelsson helped Detroit win the Stanley Cup in 2008 in his third of four seasons with the franchise. The 35-year-old Swede was limited because of injuries to 54 games and 31 points last season with Vancouver and Florida.
Detroit also signed 26-year-old forward Damien Brunner of Switzerland to a one-year, two-way contract that allows the franchise to send him to the AHL's Grand Griffins if he doesn't earn a spot on the Red Wings' roster.
Sharks sign Burrish for 4 years
Burish had six goals, 13 assists, 76 penalty minutes and a plus-6 rating last season with Dallas. He played his first four seasons in Chicago before spending the last two with the Stars. Burish has 25 goals and 29 assists in 297 career games.
"He's the type of guy you hate to play against," general manager Doug Wilson said. "You want him on your side. He doesn't care about anything other than winning."
Burish is a former linemate of Sharks forward Joe Pavelski in college at the University of Wisconsin.
Leafs sign forward McClement
The Maple Leafs have signed forward Jay McClement to a $3 million, two-year deal, hoping he can help improve their penalty kill.
McClement is a seven-year NHL veteran who spent last season with the Colorado Avalanche.
Toronto has been ranked no higher than 24th in the NHL in penalty killing since the 2004-05 lockout.
In 553 games with St. Louis and Colorado, the 29-year-old McClement has 63 goals and 177 points.
Also Sunday, the Leafs signed forward Matt Frattin to a two-year contract.
Islanders add Boyes, Carkner
The deal is worth $1 million, a source confirmed to ESPNNewYork.com's Katie Strang.
The one-time 40-goal scorer played the last two seasons with the Buffalo Sabres. In 2011-12, he recorded eight goals and 15 assists in 65 games.
The Islanders also agreed to a three-year deal with defenseman Matt Carkner.
Moss bolts Calgary for Phoenix
The Coyotes have signed right wing David Moss to a two-year contract.
Terms of the deal weren't disclosed.
Moss played his entire NHL career with Calgary after the Flames selected him in the seventh round of the 2001 draft.
The 30-year-old from Michigan struggled with injuries last season, scoring two goals with seven assists in 32 games. In 2008-09, he had career highs of 20 goals and 19 assists.
Moss has 61 goals and 63 assists in 317 career regular-season games, along with four goals and two assists in 17 playoff games.
The Coyotes also signed minor league goalie Chad Johnson to a one-year, two-way contract.
Rangers add Asham, re-sign Bickel
The Rangers have agreed to terms on a two-year deal with forward Arron Asham. The deal is worth $2 million, a source confirmed to ESPNNewYork.com's Strang.
By joining the Rangers, Asham has now been a part of all five Atlantic Division teams. He has previously played for the Islanders, Flyers, Devils, and most recently, the Penguins.
The Rangers also agreed to a contract with defenseman Stu Bickel.
The hard-hitting Bickel had nine assists in 51 games as a rookie last season. He had no points in 18 playoff games with the Rangers.
Latendresse attempts comeback with Sens
The oft-injured forward signed a $1.25 million, one-year deal after becoming a free agent Sunday.
Latendresse played 27 games combined over the past two seasons with the Minnesota Wild, scoring eight goals and 15 points.
He missed 50 games because of a concussion last year.
Ottawa also signed defenseman Mike Lundin to a one-year deal while securing prospect forward Shane Prince to a three-year entry-level contract.
Flyers re-sign G Leighton
The Flyers have re-signed free-agent goaltender Michael Leighton.
Leighton, 31, spent most of last season in the AHL, but could be a backup to Flyers starter Ilya Bryzgalov this season. Philadelphia's No. 2 last season, Sergei Bobrovsky, was dealt to Columbus during the NHL draft last month.
Originally acquired by the Flyers in December 2009, Leighton has spent part of the last three seasons with Philadelphia. He also appeared in four games for the Flyers during the 2006-07 season. In 32 career regular-season games for Philadelphia, Leighton is 19-7-2 with a 2.68 goals-against average.
He is most remembered, however, for his run in the 2010 Stanley Cup playoffs, where he set a new franchise record for shutouts in a playoff series (3), and went 8-3 with a .916 save percentage as the Flyers, seeded just No. 7, won the Eastern Conference.
"I'm very happy to be back in Philly," said Leighton, who did not talk with any other teams. "This is where I want to be and I'm excited about the team we have this year. I look forward to the opportunity."
Pens ink Glass to 2-year deal
The Penguins signed free agent forward Tanner Glass to a two-year contract.
Pittsburgh, with money to spend this offseason and eyes on bigger prizes later on, will pay Glass, 28, $1.1 million per season. The veteran had 246 hits and 51 blocked shots for Winnipeg last season, and will fill the hole created when Arron Asham signed with the Rangers earlier in the day.
"I was really fortunate in Winnipeg to play in some big situations. The penalty kill and other major responsibilities for me," Glass said. "I played against some of the top lines in the league on a nightly basis. I think those are great minutes, and you learn a lot in those minutes.
"It was just a privilege to have that much ice time last year, and I had a really good year."
Sabres add Scott
Listed at 6-foot-8 and 270 pounds, the 29-year-old Scott split last season between Chicago and the New York Rangers. He finished with just one assist in 35 games.
Undrafted out of Michigan Tech, Scott broke into the NHL during the 2008-09 season with the Minnesota Wild. Overall, he has a goal and four assists, and 236 penalty minutes in 146 career games.
General manager Darcy Regier said Scott's size and toughness will be valuable additions.
