(CBS) Blackhawks defenseman Michal Rozsival accidentally punched linesman Andy McElman during the Avalanche’s 4-2 win at the United Center last night.

The altercation started in the third period after Rozsival got into it with Colorado’s Maxine Talbot. As Rozsival and Talbot shoved and tangled, McElman skated in before catching a right hook.
