CHICAGO (AP) — Chicago Blackhawks defenseman Michal Rozsival has undergone surgery on his fractured left ankle and should be ready for the start of training camp. Rozsival was hurt when he lost his balance and fell backward in the second period of Chicago's 4-3 series-ending victory at Minnesota. David Rundblad is expected to play his first career playoff game in Rozsival's place when the Blackhawks open the Western Conference finals against top-seeded Anaheim.

— Former NHL defenseman Steve Montador had a degenerative brain disease that's been linked to repeated blows to the head, according to researchers who autopsied his brain. The 35-year-old died in February. Montador suffered multiple concussions during his career with six NHL teams. His brain was donated to the Canadian Sports Concussion Project in Toronto for analysis. Montador's family said they plan to launch a lawsuit against the NHL. Montador had suffered from depression, erratic behavior and memory problems.
