Bednar said Rantanen will benefit from starting the year in the AHL and having three NHL practices before the club's next contest.
"He played some games, had a week of practice, played a couple more games and now is back up," the Avs coach said. "So he has three more days of practice with us to get ready for his first one with us this year."
Friday's contest won't be Rantanen's first in the league, as he played nine games in two separate stints with the Avalanche last season. The Finland native was on the club's opening-night roster in 2015-16 and was later called up for three contests in March after a dominating campaign in San Antonio.
He led the Rampage in all three scoring categories with 24 goals, 36 assists and 60 points, was a member of the league's Second All-Star and All-Rookie teams and shared the AHL's outstanding rookie award.
That's not a bad haul for his first-ever campaign in North America.
"It's a lot different then what we play in Europe, like what I'm used to. It helped me a lot," Rantanen said of playing most of last season in San Antonio. "This year is a lot easier to come here and play. You know what to expect, so it's going to be easier."
