Kadri, who appeared to twist his left leg as he back-passed the puck after the faceoff, returned to the ice for the third period and played one shift before returning to the locker room.
Avalanche coach Jared Bednar confirmed Kadri's injury was lower-body, and said that Kadri will be re-evaluated when the team gets back to Denver on Monday.
"I have not talked to the trainers," Bednar said. "He left at the start of the third period. I thought he'd be able to come out and try it [in the third], and it didn't go so well. So it's probably a smart decision -- if he's unable to play 100 percent -- to come out of the game. So, we supported him in that. And we'll see where it goes when we get back."
Kadri, 29, had an assist in the win, taking 14 shifts with 10:06 on the ice. He has been a key cog in the Avalanche's stellar season, with 19 goals and 35 points in his first season in Colorado.
Kadri played parts of 10 seasons with the Maple Leafs before signing with Colorado in the offseason.
The Avalanche are in second place in the Central Division and have won four in a row.
