Chicago Blackhawks defenseman Michal Rozsival left Game 4 of the Western Conference Second Round against the Minnesota Wild in the second period with a leg injury.
Rozsival was injured with 13:23 remaining after falling awkwardly. He was unable to put weight on his left leg and needed to be helped off the ice and to the locker room.
Rozsival played 7:16 in Game 4 and was averaging 18:34 in the Stanley Cup Playoffs as one of five defensemen used primarily by Chicago.
Chicago led the best-of-7 series 3-0 and was trying to reach the Western Conference Final for the fifth time in seven seasons.
