Avalanche defenseman Nikita Zadorov finally reported to training camp Thursday morning, nearly a week after signing a contract extension. The 22-year-old Russian was held up in Ottawa, Ontario, because of issues with his immigration papers. “It usually takes a few days to get it,” Zadorov said from the Pepsi Center, where some of his teammates had participated in a morning skate in preparation for Thursday’s preseason game against the Dallas Stars. “With the situation with Russia and America right now, it’s kind of tough. But it’s nice to get it done.” Zadorov had a physical and off-ice testing, before watching the Avs score three times in the first 5:09 of the game and gonwent on to beat Dallas 5-1. He will practice with the team Friday in split-squad sessions at Family Sports Center. Colorado visits the Minnesota Wild on Saturday to begin a four-game stretch in six days to wrap up the exhibition season. “I have a few preseason games left, right? So I’m going to play some of them and hopefully get my level back right away,” said Zadorov, who has been training in Ottawa. “But I’ve been skating great. … Let’s get the season going already. I’m ready.”
