The Lightning have lost four man-games to injury among their defensemen in 16 playoff games. Besides Cernak in Game 5 against the Islanders, David Savard was out the first three games of the second round against the Hurricanes with an upper-body injury.
They have used seven defensemen in the playoffs.
"The guys were going pretty good there for the last number of games," Schenn said. "I played the first three against Carolina, and after that everyone was healthy and guys were playing great so obviously you just stay patient, try to work and be supportive of the guys, cheer them on for wins. The longer you go it's tough to stay healthy every single game for the playoffs."
However, an 8-0 win allowed the defensemen who typically log heavy minutes, especially when they have to make up for players missing time because of injury, a reprieve.
Hedman played a playoff-low 20:43, including 4:27 in the third period, when the Lightning were down to five defensemen with Rutta out. He's averaging a team-high 24:33 of ice time per game in the playoffs.
"My body feels fresh," Hedman said.
Ryan McDonagh played 19:27, also a playoff low. The defenseman is second on the Lightning with 22:46 of ice time per game.
Savard and Mikhail Sergachev picked up additional ice time in the third. Savard played 10:03 and Sergachev skated 9:29.
"Any time at this time of the year you can give the guys a little bit of a break that play strong minutes, you have to," Cooper said. "It doesn't come around that often. I don't anticipate there being a game like last night, but you get a break. On their side they were trying to do the same thing. Both teams probably had a similar thought process in let's move ahead for Game 6."
