The University of Wisconsin men's hockey team faces the prospect of opening the season without one of its top defensemen.

K'Andre Miller has been suspended for a violation of team rules, associate head coach Mark Osiecki said Saturday.

Miller was the only player not present Saturday when the team practiced at the Kohl Center.

Osiecki said Miller's absence was related to the suspension, but Miller is still with the team and involved in off-ice workouts. Osiecki, who was in charge of practice in the absence of head coach Tony Granato, didn't divulge the reason for the suspension.
