The 56-game, intradivisional schedule doesn't have much downtime, limiting the time for goalies to get off the ice and allow for physical and mental recovery.
Some teams have gotten creative.
For those with the flexibility to carry three goalies on the active roster, the use of the third-string goalie on game days has provided the opportunity for the starter to rest.
"It's not a day off just because you're backing up," Toronto Maple Leafs goalie Frederik Andersen said. "When you think about it, even when you are backing up you are still spending six hours at the rink. You still have to do all your pregame warmups. You still have to be somewhat ready. You still have to be on."
The Maple Leafs, Anaheim Ducks and New Jersey Devils each have dressed their third goalie as the backup this season, giving their No. 1 a complete day off. In an already demanding season, it's recognition that dressing as a backup goalie isn't much of a break.
Toronto, which has had two or more days off between games three times so far this season, including their current stretch between a 2-1 overtime win at home against the Calgary Flames on Wednesday and a game at the Edmonton Oilers on Saturday (7 p.m. ET; NHLN, CBC, SN, CITY, TVAS), was the first to do it. They let Andersen sit out the third game of the season, against the Ottawa Senators, which was the second game of a back-to-back and Toronto's third game in four nights. Jack Campbell started and Aaron Dell, who since has been claimed on waivers by the New Jersey Devils, was the backup that night.
