DENVER — Chicago Blackhawks defenseman Artyom Levshunov insisted the nerves were nonexistent ahead of his NHL debut against Colorado. Excitement sure, but no pregame jitters for the No. 2 overall pick in the 2024 draft. The 19-year-old from Belarus held up quite well, too. He skated for almost 21 minutes in a 3-0 loss to Nathan MacKinnon and the high-flying Avalanche. The game was scoreless before the last-place Blackhawks faltered in the third period. The 6-foot-2, 208-pound Levshunov missed the start of the season because of a fractured right foot. He was recalled by Chicago on Sunday from Rockford of the American Hockey League.
