Seguin missed 10 games late last season with a knee injury, and in his absence several players took on added responsibility. Nill said he sees no reason that won't also be the case this time.
"This is an opportunity for everybody," he said. "It's no different in our back end with the defense. All year we had no injuries and we kept talking about our depth. Now we see where the depth's at, and it's paying off for us. Same thing with the forward position. We got lots of depth, lots of good players. It's an opportunity for somebody else now."
Ruff did have some positive injury news Friday. Defenseman John Klingberg, out the past six games with a lower-body injury, could return Saturday.
"Klingberg is definitely a possibility [for Saturday]," he said. "See how he made it through today. I thought [Thursday] was an option, which turned out not to be, so I would hope after today's practice and some extra work today, a little bit more fitness in the gym afterwards, that he'd be close to being ready for us."
Defenseman Jordie Benn, who has missed the past seven games with a lower-body injury, is day-to-day but could return during a road trip that starts Tuesday against the Blackhawks and includes games March 24 at the Arizona Coyotes and March 26 at the San Jose Sharks.
"Close [to returning]," Ruff said. "I'd put him in the day-to-day category. Not likely for [Saturday]."
