After revealing their initial roster yesterday for the upcoming World Championship, Hockey Canada announced (Twitter link) that Blues goaltender Joel Hofer and Wild defenseman Jacob Middleton have been added to the roster. Hofer spent most of the season with AHL Springfield but didn’t look out of place in six games with St. Louis where he posted a .905 SV%. He’s expected to be the backup for the Blues next season and will compete for playing time in this event with Buffalo’s Devon Levi and Montreal’s Samuel Montembeault.
