Chicago Blackhawks star forward Patrick Kane was placed on long-term injured reserve after suffering an upper-body injury in Tuesday's 3-2 shootout win over the Florida Panthers.
Kane was cross-checked in the lower back by Panthers defenseman Alex Petrovic at 7:49 of the first period, stumbled and fell awkwardly into the boards, with his left shoulder appearing to absorb most of the impact.
Petrovic, who received a two-minute minor penalty, will not have a disciplinary hearing for the hit.
Kane is tied for the NHL lead with 64 points and leads the Blackhawks with 27 goals and 37 assists in 61 games this season.
The Blackhawks also recalled forward Teuvo Teravainen from Rockford of the American Hockey League and assigned defenseman Trevor van Riemsdyk to the AHL on Wednesday.
Teravainen, 20, has two goals and two assists in 15 games for the Blackhawks this season.
Van Riemsdyk has been recovering from surgery to repair a left patella fracture suffered in mid-November.
>>Penguins Edge Caps
Chris Kunitz scored the winner in the third period and Evgeni Malkin added three assists, as Pittsburgh avoided a season-series sweep thanks to a spirited 4-3 victory over Washington at Verizon Center.
Brandon Sutter, Patric Hornqvist and Sidney Crosby also lit the lamp for the Penguins, who have won three in a row and were aided in their latest triumph by a glut of power-play chances in the middle frame.
Marc-Andre Fleury picked up the win thanks to a 21-save effort.
John Carlson, Troy Brouwer and Alex Ovechkin tallied for the Capitals, who had outscored their rivals by a 10-1 count in winning the first three games between the clubs.
