Alex Galchenyuk is entering the NHL and NHLPA's player assistance program after being arrested last week, sources told ESPN, and has apologized to police for his "deeply disrespectful and despicable behavior."

Galchenyuk was arrested July 9 in Scottsdale, Arizona, for a hit and run incident that resulted in the Arizona Coyotes terminating his contract just 13 days after signing the 29-year-old as a free agent.

Tanner Jeannot, a restricted free agent forward acquired last season in a trade with the Nashville Predators, signed a two-year contract with the Tampa Bay Lightning on Saturday.

The deal carries an average annual value of $2.665 million, Tampa Bay general manager Julien BriseBois announced in a statement, and assures the Lightning offense another rough-and-tumble winger who might see a spike in production now that he'll have a full season in coach Jon Cooper's system.

The Philadelphia Flyers will buy out the last season of defenseman Tony DeAngelo's contract, making him an unrestricted free agent and ending his turbulent tenure with the team.

General manager Daniel Briere announced Friday that DeAngelo had been placed on unconditional waivers.

Vladimir Tarasenko, one of the most notable names available in NHL unrestricted free agency, has changed agents as he seeks a new contract.

Tarasenko, 31, is now represented by JP Barry and Pat Brisson of CAA, as Brisson confirmed to ESPN on Wednesday. CAA represents some of the NHL's biggest names, including Sidney Crosby and Patrick Kane.

Unrestricted free agent forward Zack MacEwen signed a three-year, $2.325 million contract with the Ottawa Senators on Thursday.

MacEwen, who will turn 27 on Saturday, recorded 10 points (four goals, six assists), 66 penalty minutes and 150 hits in 56 games last season split between the Philadelphia Flyers and Los Angeles Kings, who acquired the rugged forward ahead of the trade deadline.

The Pittsburgh Penguins signed forward Andreas Johnsson to a one-year, $800,000 contract, president of hockey operations Kyle Dubas announced Friday.

Center Max Domi signed a one-year, $3 million contract with the Toronto Maple Leafs on Monday, following in the footsteps of his father, Tie Domi, who played parts of 12 seasons for the franchise.

Max Domi, 28, authored a bounce-back season and was taking up major minutes up front for the rebuilding Chicago Blackhawks when the Dallas Stars traded for him in March in time for their postseason push.

The Toronto Maple Leafs on Sunday agreed to a one-year contract with free agent forward Tyler Bertuzzi, one of the more sought-after veterans on the market this summer.

The deal will carry a salary cap hit of $5.5 million, a source told ESPN's Kristen Shilton, and will keep Bertuzzi in the Atlantic Division after he finished last season with the Boston Bruins.

The Nashville Predators, who made a big splash earlier on Saturday, signing center Ryan O'Reilly during the opening of free agency, continued to add later in the day, agreeing to a two-year, $6.37 million contract with forward Gustav Nyquist.

The Arizona Coyotes stayed busy on the first day of free agency, signing veteran forward Alexander Kerfoot to a two-year, $7 million contract, sources told ESPN's Kristen Shilton on Saturday night, confirming reports.
