During practice Wednesday, Michal Rozsival wore a full-face visor. Entering the locker room, he wore a cap, and just a few inches below it he wore a black patch of stitches on an upper lip that looked like it had been inflated by a tire pump. And this was the veteran Blackhawks defenseman looking and feeling fortunate. “Nothing broken, no teeth missing,” Rozsival said. “Could have been worse, so I’m very lucky.” Remarkably so, actually, after a puck off the stick of the Oilers’ David Perron lasered into the Hawks bench Sunday and caught an unaware Rozsival directly in the mouth, literally knocking him off his seat. “He could have got hit in a variety of places that would have caused some serious damage,” Hawks coach Joel Quenneville said. “He was fortunate it was just stitches and some pain. Little higher, little lower, would have been trouble.” But all Rozsival endured after that was about a half-hour of fix-up, he said, and he practiced Wednesday with the intent to play against the Coyotes on Thursday — though unsure if he’ll don the visor. This while also blaming himself for the incident in the first place. “The thing is, I wasn’t watching the play, I didn’t see the puck coming,” Rozsival said. “So it kind of caught me by surprise. I got kind of knocked out, like sucker-punched. I’m glad it is what it is — just a cut and it should be fine.” Next man in: Winger Jeremy Morin has idled as a healthy scratch for three games, replaced by veteran and converted defenseman Sheldon Brookbank on the third line. The 22-year-old Morin should have another chance Thursday to return to the lineup and stay there against the Coyotes. “You get back in there, you want to bring energy and you want to make sure you play your game and basically play to your strengths,” Quenneville said. “But, defensively, make sure you’re doing the right things within the team structure.”
