Head coach Jared Bednar had said that Landeskog got hurt in one of the games prior to that home contest against the Ducks, but the injury didn't reveal itself until the forward had some "discomfort" during the team's practice on Oct. 27.
Bednar said following Monday's on-ice session that Landeskog was going to see the doctor during the day in a pre-scheduled visit to see where he was at in his recovery.
"Seeing the doc today for some more imaging," Bednar said on Monday. "Hopefully that goes well and he can start to progress, but we'll wait on the doctor's information. We should know more tomorrow."
Landeskog recorded three goals and four assists in the first 11 contests of the season.
Once the team session began, there was more good news as both Erik Johnson and Mikko Rantanen participated, with the latter doing so in a regular practice jersey.
It was Rantanen's first full-contact practice since suffering a lower-body injury on Oct. 21 at the St. Louis Blues. Depending on how the forward felt, Bednar said on Monday that Rantanen was close and could possibly return to the lineup as early as Wednesday, but Rantanen said after practice that he won't play until the weekend.
Rantanen skated during 5-on-5 drills on a line that also included Vladislav Kamenev, Logan O'Connor and T.J. Tynan. Rantanen also took some reps with the Avs' power-play units.
Johnson practiced in a red, non-contact jersey after being held out of Monday's session. Bednar called the defenseman "sore" after he was cross-checked headfirst into the boards by the Toronto Maple Leafs' Alexander Kerfoot in Colorado's previous game on Saturday. The play resulted in a two-game suspension for Kerfoot.
The Avalanche closes a two-game homestand on Wednesday versus the Edmonton Oilers before traveling to face the Chicago Blackhawks in a home-and-home, back-to-back set that begins Friday.
