Originally listed as week-to-week, Rantanen said he is on schedule in terms of his recovery.
"We kind of knew it was going to take a while," he said. "Those things, especially early in the year, you don't want to go too early and then hurt it again and then be out more than you're supposed to."
At the time of his injury, Rantanen was tied for the club lead in points (12), goals (five) and game-winners (two) in nine games. Despite missing the past five weeks, Rantanen's 12 points are tied for sixth on the Avalanche in scoring.
Rantanen's injury was the start of a wave of ailments that the Avs have had to deal with. Since then, Colorado has also been without Pierre-Edouard Bellemare (concussion, one game), Matt Calvert (head, three games presently), Pavel Francouz (concussion, two games), Philipp Grubauer (lower body, five games), Tyson Jost (upper body, three games), Gabriel Landeskog (lower body, 12 games presently), Colin Wilson (lower body, 12 games presently) and Nikita Zadorov (head, three games), and Erik Johnson is questionable for Wednesday's contest after being pushed headfirst into the boards in the previous outing against the Toronto Maple Leafs. Johnson was a non-contact participant at Tuesday's practice.
"Obviously injuries are the toughest mentally," Rantanen said. "You go out and you want to help the team, but you're out for four, five weeks. It's not the easiest thing but it's part of this sport and all the sports. You just have to go through it."
