A groin injury appears to have ended Casey Mittelstadt's season.
The Buffalo Sabres and their 19-year-old center hoped USA Hockey would select Mittelstadt for its World Championship team. The United States unveiled its initial roster Saturday, and Mittelstadt failed to make the cut.
A groin injury is said to be the culprit.
USA Hockey named 23 players to its roster, which will play in Denmark next month. Teams have a limit of 25 players, and space is usually kept available for NHL players who are eliminated during the second round of the playoffs.
Mittelstadt, who represented the United States at the World Junior Championship, signed with the Sabres last month after finishing his freshman year at the University of Minnesota. He played in six games for the Sabres, recording one goal and four assists.
The U.S. roster features Buffalo-born forward Patrick Kane of the Chicago Blackhawks. The team also includes forwards Cam Atkinson, Blake Coleman, Alex DeBrincat, Johnny Gaudreau, Brian Gibbons, Chris Kreider, Dylan Larkin, Anders Lee, Sonny Milano, Derek Ryan, Tage Thompson and Colin White; defensemen Will Butcher, Quinn Hughes, Nick Jensen, Alec Martinez, Connor Murphy, Jordan Oesterle and Neal Pionk; and goaltenders Scott Darling, Keith Kinkaid and Charlie Lindgren.
