CHICAGO (CBS) Blackhawks defenseman Chris Campoli and forward Viktor Stalberg both filed for arbitration Tuesday, the last day they could do so under league rules.

Campoli and Stalberg are among 23 NHL players who filed for arbitration. Hearings will be held in Toronto from July 20 to August 4.

Campoli filed for arbitration last summer with the Ottawa Senators but settled before his hearing.
