NHL: Calvin de Haan, Danny DeKeyser sign PTOs, and Mathieu Perreault retires
Several free agents remain unsigned led by defenseman P.K. Subban. With NHL Training Camps less than two weeks away, teams are signing some of those players to Professional Tryout Contracts (PTO).
What is a PTO? It’s basically a contract that teams can offer unsigned free agents in order to invite them to training camp. This will give the club a closer look at a potential free agent they may want to sign.
Calvin de Haan and Danny DeKeyser sign PTO’s
On Friday, the Carolina Hurricanes announced they’ve invited defenseman Calvin de Haan to training camp on a PTO.
De Haan, 31, recorded 8 points in 69 games for the Blackhawks with a cap hit of $4.55M AAV. Despite playing for a bad Chicago team, he can add depth to a defense.
Also on Friday, the Vancouver Canucks announced Danny DeKeyser will be at camp on a PTO. The former Red Wings veteran rearguard just wrapped up a 6-year deal with an AAV of $5 million and there were no takers on the free agent market likely due to injury concerns.
DeKeyser, 32, picked up 11 assists in 59 contests last season.
Update: Zach Aston-Reese has signed a PTO with Toronto Maple Leafs.
Mathieu Perreault has retired

Mathieu Perreault has retired after 13 NHL seasons.
The 34-year-old spent last season with the Montreal Canadiens and the team acknowledged his recent retirement on its Twitter account on Thursday.
“Wishing Mathieu Perreault a happy retirement and congratulations on a 13-season NHL career,” the Canadiens said.
Perreault is joining a show on Canadian-based TVA Sports, the network announced earlier Thursday.
Perreault had nine points (four goals, five assists) in 25 games for Montreal last season. He scored a goal in his final game on April 29 against the Florida Panthers.
Overall, he had 143 goals and 209 assists (352 points) in 708 career games. He scored 15 or more goals in a season five times.
