He seems to be enjoying the homecoming. He has four goals and three assists in six games.
"It's home, so it's been unbelievable," Datsyuk said. "It's part of my life now."
Because of the World Cup, Datsyuk will return to North America temporarily and face a lot of familiar faces from his not-so-distant NHL days. The tournament will be held at Air Canada Centre in Toronto.
Team Russia plays its preliminary-round opener against Team Sweden on Sept. 18 (3 p.m. ET; ESPN, SN, TVA Sports). Although Datsyuk will have a chance to catch up with some old friends while in Toronto, he made it clear, "We're coming here to work."
"But of course when you have time to see people, friends, you can," he said.
GETTING IN LINE:With the four KHL players joining the group, practice Tuesday provided a more complete look at Team Russia's forward lines. After skating with Chicago Blackhawks teammate Artem Anisimov and Vladislav Namestnikov of the Tampa Bay Lightning on Monday, left wing Artemi Panarin was reunited Tuesday with former SKA St. Petersburg linemates Vadim Shipachyov and Evgeny Dadonov.
Datsyuk centered the fourth line between Ivan Telegin, who plays for CSKA Moscow in the KHL, and Namestnikov, with Anisimov rotating in.
The top line of Alex Ovechkin, Evgeny Kuznetsov and Nikita Kucherov, and the second line of Nikolay Kulemin, Evgeni Malkin and Vladimir Tarasenko, remained intact from Monday.
Team Russia coach Oleg Znarok said the top three lines are set, but he has a decision to make on the fourth line.
Panarin, Shipachyov and Dadonov had great success as a line in helping SKA St. Petersburg win the Gagarin Cup in 2014-15. Panarin led that team that season with 62 points (26 goals, 36 assists) in 54 regular-season games. Shipachyov was third with 54 points (12 goals, 42 assists) and Dadonov was fourth with 46 points (19 goals, 27 assists).
Following that season, Panarin signed with the Blackhawks and won the Calder Trophy last season after leading NHL rookies with 30 goals, 47 assists and 77 points.
CAPTAIN COMING:Znarok said a decision on Team Russia's captain and alternate captains likely would be made later in the day Tuesday, with an official announcement expected Wednesday.
Datsyuk served as Russia's captain for the 2014 Sochi Olympics.
