The Flames will be missing a goal for two weeks while the Lightning will be without a key forward for almost a month.
Calgary Flames goalie Miikka Kiprusoff will miss another two weeks with a slight Grade 2 MCL sprain, the team announced Tuesday.
Kiprusoff was hurt at the end of the second period Feb. 5 against the Detroit Red Wings, when he and Johan Franzen collided near the net.
The Flames claimed veteran goalie Joey MacDonald off waivers to replace Kiprusoff. He will pair with rookie Leland Irving.
Meanwhile, Tampa Bay Lightning forward Ryan Malone will miss 3-4 weeks with a lower-body injury, head coach Guy Boucher told the Tampa Bay Times.
The team placed Malone on injured reserve after he was hurt warming up ahead of Sunday's loss to the New York Rangers.
"He was just warming up before the game, and it tightened up," Lightning general manager Steve Yzerman told the paper, adding that the injury could be muscle-related, rather than anything structural.
---The Boston Bruins signed forward Jay Pandolfo to a one-year, two-way contract that will pay $600,000 if the veteran forward plays in the NHL.
Pandolfo, 38, will earn $350,000 in the AHL. He had been with the team on a professional tryout contract since Jan. 13.
He had a goal, two assists and a minus-14 rating in 62 games with the New York Islanders last season. He has spent 13 of his first 14 NHL seasons with the New Jersey Devils.
---The Philadelphia Flyers have recalled forward Harry Zolnierczyk from their Adirondack affiliate, and sent Sean Couturier home to recover from the flu, according to multiple reports.
The Glens Falls Post-Star report said Zolnierczyk will join the team in Winnipeg.
Zolnierczyk, 25, has nine goals and eight assists for 17 points in 46 games with the Phantoms. He also appeared in 33 games with the Flyers last season.
