Bednar says he doesn't think the rear guard will miss more than the Avalanche's next two games and could return for the Feb. 2 matchup versus the Vancouver Canucks.
"I'm encouraged by the way he is feeling this morning that he's not going to be (out) long term," Bednar said. "We obviously have an eight, nine-day break (coming up). So even if he misses the next two games, we're hoping he'll be back and ready to roll as soon as we come out of that break."
Johnson only played 2:01 and three shifts on Saturday versus the Los Angeles Kings before leaving midway through the first period of the Avalanche's 7-1 victory.
The Avs' upcoming games will be the first this season that Johnson will miss. In 48 outings, he is second among club defenders in scoring with 14 points (three goals, 11 assists) and leads the entire roster in shifts per game (26.8) while ranking third in average ice time (21:42).
Colorado did receive some positive news on the injury front, as forward Mikko Rantanen should play against the Predators after not skating in the third period against the Kings due to a "lower-body tweak."
"Sigh of a relief for everyone, including me," Bednar said. "He is such a big part of our team, but he feels good this morning, wanted to practice. He'll be in tomorrow afternoon."
Rantanen, who leads the team and is tied for second in the league in scoring with 73 points, said he was held out of the final 20 minutes versus L.A. as more of a precaution as the team had built a comfortable 7-0 lead at the time.
"We had a good two periods, so no point to do anything stupid there, but everything is good for tomorrow," Rantanen said.
