Kasper (upper body) won't play Sunday against Winnipeg, Helene St. James of the Detroit Free Press reports.
Kasper didn't participate in Saturday's practice and is still being evaluated. He had four shots on goal and five PIM over 10:50 of ice time against the Rangers on Friday. However, he wasn't injured in his second-period fight with Rangers defenseman Sean Durzi. Carter Mazur will probably play against the Jets on Sunday because of Kasper's absence.
