CHICAGO - The Chicago Blackhawks have placed defenceman Michal Rozsival on long-term injured reserve.

The Blackhawks also recalled defenceman Ville Pokka from Rockford of the American Hockey League and assigned defenceman Viktor Svedberg to the IceHogs.

Rozsival broke his left ankle in Game 4 of Chicago's second-round sweep against Minnesota in the playoffs. He re-signed with the Stanley Cup champions last month.

The Blackhawks host the New York Rangers in their season opener on Wednesday night.

The team announced the moves on Tuesday.
