When the lineup cards came in for Game 4 of the Western Conference final between the Chicago Blackhawks and the Detroit Red Wings, no one expected what they saw.

The Wings lost captain Nicklas Lidstrom for the contest, while Chicago's Martin Havlat made a surprising return to the ice two days after taking a crushing hit from defenceman Niklas Kronwall.

Also, Blackhawks starting goalie Nikolai Khabibulin is out of Game 4 with an upper body injury, and backup Cristobal Huet will take his place in net.

The 39-year-old Lidstrom suffered a lower body injury sometime during Game 3. He has been a tower of strength for the Wings in the playoffs, with four goals, nine assists, and a plus-seven rating in 14 games.

Chris Chelios will take his place in the lineup.

Havlat, meanwhile, is two days removed from being knocked out (literally) of Game 3 when Kronwall smoked him in the first period. Havlat lay on the ice motionless for a minute or so after suffering a suspected concussion and was helped to the dressing room by a trainer and teammates.

But the Blackhawks' leading scorer made a dramatic recovery, and looked well enough in the pre-game skate to suit up for the contest.

Chicago goalie Khabibulin hurt himself at some point in Game 3 and was pulled after the second period in favour of Huet.
