Benn said his first two weeks of rehab have included little activity, but he hopes to start ramping things up next week.
"Well, the last two weeks have been pretty boring, not doing too much, letting it heal and recover," Benn said. "Doing little exercises here and there, but I think this week I could be able to pick it up a bit and possibly even skate later in the week."
Benn and teammate Tyler Seguin, who missed all but one of Dallas' playoff games with calf and Achilles injuries, will have their first Team Canada practice Sept. 5. The World Cup runs through Oct. 1 at Air Canada Centre in Toronto.
A fifth-round pick (No. 129) at the 2007 NHL Draft, Benn, who won the Art Ross Trophy as the League leader with 87 points in 2014-15, has 192 goals and 448 points in 508 regular-season games.
Benn has been Stars captain the past three seasons and said the thought of leaving Dallas never entered his mind during the two-week negotiation process between the Stars and his agent, Rich Evans.
"I fell in love with Dallas, Texas ever since I got down here," Benn said. "Here I am sticking around here year-round. I have all the belief in [general manager] Jim Nill and the coaching staff around here that we're going to do something special. [Nill] is a smart man, he's an unbelievable guy and an easy guy to talk to. I've definitely built a relationship around him. We have the same goals and I want to do it as a Dallas Star."
When Benn's extension begins after this season, he will be tied with Evgeni Malkin of the Pittsburgh Penguins for fourth-highest average annual value ($9.5 million) in the NHL, according to General Fanager. Only Patrick Kane and Jonathan Toews of the Chicago Blackhawks ($10.5 million), Anze Kopitar of the Los Angeles Kings ($10 million) and Alex Ovechkin of the Washington Capitals ($9.538 million) are ahead of Benn.
